Two Sunday Mornings, One Cross
Cornerstone Baptist Church sits on Cornerstone Drive in Windsor, Colorado, a town just north of Denver where the Front Range begins to flatten into farmland. The congregation gathers twice each Sunday morning for worship, at 8:00 and 10:30, with Sunday School for everyone in between at 9:30. Both services are streamed live on Vimeo and archived for on-demand listening and viewing, so neighbors who travel, work weekends, or live farther afield can keep up.
The three-hour rhythm is a deliberate rhythm. People arrive early for the first service, return for classes and teaching across every age group, then come back for the second service that includes Children's Church. Newcomers who arrive for either hour will find greeters, hosts, ushers, and a resource table ready through the church's First Impressions ministry. The aim, the church says, is simply to make sure each person is greeted, directed, treated, and seated so they can give their full attention to what is happening in the room.
Worship That Ranges from Hymns to the Latest Songs
Worship at Cornerstone is intentionally broader than a single style. The church describes worship itself as more than music, calling it pursuing the heart of God in song and Bible study and silence and prayer and dedication and giving. Musically, the team includes singers, guitars, drums, percussion, keyboards, and piano, and their repertoire runs from the older sacred hymns to the songs currently heard on Christian radio. The result is a blended service that older members and younger families can share.
Anyone interested in joining that team can write to Worship Minister Jarrett Slusher. A written handbook spells out the ministry's values and expectations, and the team's Sunday morning work can also be sampled on the church's YouTube channel.
A Preacher Who Preaches with His Shoes Off
Senior Pastor Tree Cooper has led Cornerstone since February 2017. He and his wife Robbin, married in 2006, share a February 18 birthday and are raising three children, Anna, Joshua, and Daniel. Pastor Tree preaches expository sermons that move straight through a passage of Scripture and tie it back to the larger biblical story, always aiming to send people home with practical steps for the week ahead. His main translation is the New American Standard Version, with regular use of the King James and Holman Christian Standard, and he often preaches from the original Greek.
He also preaches barefoot. The reason is small but worth knowing. When God met Moses at the burning bush, He told him to take off his sandals because he was standing on holy ground. Pastor Tree removes his shoes at the pulpit to remind himself, and the room, of the holiness and weight of the Word of God. He is quick to add that the shoes come right back on afterward.
His background includes studies at Hardin-Simmons University, Howard Payne University, and Gateway Seminary, and Cornerstone is affiliated with the Southern Baptist Convention and the Colorado Baptist General Convention. He is the front door for anyone wanting to talk about joining the church, taking the Cornerstone 101 membership class, or beginning a relationship with Jesus.
What Cornerstone Believes
The church's teaching lines up with historic evangelical Baptist convictions. The congregation confesses one God who exists eternally in three co-equal persons: Father, Son, and Holy Spirit. Humans are made in the image of God but are marred by sin, the attitude of disobedience that separates people from their Creator. Eternity is real, and where a person spends it depends on whether they have been restored to God through faith in Jesus Christ. Heaven and Hell are described as real places of eternal existence, with Hell being separation from God and eternal life being union with Him.
Salvation, in Cornerstone's statement of faith, is a gift from God and cannot be earned by self-improvement or good works. Eternal life begins the moment a person receives Jesus Christ by faith, and that salvation is held secure by the grace and power of God. Believers are still expected to live a new life; inactive faith, the church says with James 2 in mind, is not faith at all. The Holy Spirit lives in every Christian from salvation, providing power for living, understanding of spiritual truth, guidance, and gifts for serving others. The Bible, both Old and New Testaments, is treated as God's Word written by human authors under the supernatural guidance of the Holy Spirit and as the supreme source of truth for daily living. The church is described as the body of Christ, and every believer is seen as a minister according to the gifts God has given them.
Anyone exploring those claims for the first time is invited to read the full statement of faith and to follow the church's How Can I Be Saved? page, which walks through John 3:16, Romans 3:23, and Acts 4:12 and offers a sample prayer of commitment.
Children, Nursery, and Awana
Cornerstone's children's ministry stretches across the whole Sunday morning and into the middle of the week. Sunday School for ages 4 through 5th grade meets at 9:30, and Children's Church for ages 4 through 3rd grade runs during the 10:30 worship service. Nursery care is offered for babies and toddlers up to age 3, both during Sunday School (9:30 to 10:25) and the second service (10:30 to noon). The nursery team, led by Nursery Ministry Leader Kimberly Nelson, builds each hour around Bible stories, play, and the steady presence of caring volunteers.
On Wednesdays from 6:00 to 7:30 p.m., the church fills with the louder kind of fun through Awana, a Bible club for children age 3 (by June 1, fully potty trained) through 5th grade. The year runs from September 9 to April 28 and is built around Scripture memory, game time, and small-group teaching with trained leaders. Families can register through the Awana registration page, follow the Awana Facebook page, or join the GroupMe reminders list for the latest updates. Questions go to wcbcawana@gmail.com.
WCSM: Middle and High School Students
Windsor Cornerstone Student Ministries, known on the church grounds as WCSM, gathers 6th through 12th graders who want to grow in their relationship with God and one another. The youth meet on Sunday mornings from 9:30 to 10:15 in a hybrid Sunday School and discussion format, then again on Wednesday nights from 6:00 to 8:00, opening with fellowship, snacks, and prayer before moving into worship, reflection, and a discussion-based Bible study. A two-year Old Testament reading plan is available to students who want a longer walk with the text.
Youth Pastor Jesse Wyrick and his wife Ashley are the steady faces of the ministry. He holds a Bachelor of Arts in Christian Ministries from Midwestern Seminary and a Master of Theological Studies from Gateway Seminary. Parents who want to talk through their student's place in the ministry can reach him at students@windsorcornerstone.org. The ministry keeps its own Facebook page and an Instagram account, @cbc_youth316.
Generations of Grace: Women's Ministry
The women's ministry at Cornerstone gathers under the name Generations of Grace, anchored in Ephesians 3:14-21 and a simple sentence: women of every generation, rooted in love, growing in faith. The stated goals are growing in faith, establishing relationships, being rooted in discipleship, being filled to overflow, and giving glory to God throughout all generations.
Two weekly Bible studies anchor the week. Women of the Word meets on Tuesday mornings at 9:00 at the church, and a Ladies Bible Study meets on Friday mornings from 9:00 to 10:30. Once a month, on the second Saturday, ladies of any age come together for the Generations of Grace Potluck Brunch from 9:00 to 11:00, with coffee, conversation, a dish to pass, and childcare provided. Women's Ministry Leader Amber Selgren keeps the calendar and can answer questions about getting involved.
Band of Brothers and Bibles and Bacon: Men's Ministry
The men's ministry at Cornerstone is built around brotherhood and a good breakfast. Band of Brothers, the weekly men's Bible study, meets every Friday morning at 6:00 a.m. at the church building, an early hour that makes room for the rest of the workday. Once a month, on the last Saturday, the men trade pews for pancakes at Bibles and Bacon, a 7:00 a.m. gathering at Doug's Diner on Pointe Plz Drive in Windsor.
Men's Ministry Leader Justin Webb, who can be reached at brothership@windsorcornerstone.org, oversees both rhythms and the seasonal regional gatherings that show up on the church calendar. Younger men have their own Bible study on Tuesday evenings led by Jake Sorrentino, and an additional LIFE Group for men ages 18 to 30 also gathers on Tuesday evenings under his care.
L.I.F.E. Groups Across Windsor
The L.I.F.E. Groups at Cornerstone are the church's midweek small-group network, meeting on different days throughout the week in homes around the Windsor area. The hosts and their focuses are listed openly: Tree and Robbin Cooper host a multi-Age group on Sunday evenings; Mike and Larissa Haub host another multi-Age group on Sunday evenings; Tom and Sandy Macy host Sunday afternoons without childcare; Jeff and Donna Gallagher host Tuesday evenings without childcare; Jonathan and Teegan Schlagel host Thursday evenings for college and young adults, both single and married; Charles and Cinda Hardin host a group geared toward empty nesters; Jeremy and Susan Carter host a group called Connected in Chaos for families with teens; and Jake Sorrentino hosts Men on a Mission for men ages 18 to 30. Childcare is available in many of the groups.
L.I.F.E. Group Coordinators Jon and Tonya Robinson help newcomers find a group that fits.
Sunday School for Every Age
The 9:30 Sunday School hour at Cornerstone is a small map of the whole church. Adults can choose between Walking in the Word, led by Jody Niswender, and Living the Dream, led by Brian Knifong. Students in 6th through 12th grade meet under Youth Pastor Jesse Wyrick. Children are divided into a preschool class for ages 3 to 5 and an elementary class for kindergarten through 5th grade, led by Laura Jackson and the Children's Ministry Team, with a separate nursery class for the youngest children. Anyone unsure where to start can write to Pastor Tree.
Mission Mindset and Shoeboxes
Cornerstone teaches that God has called every believer to mission, whether international, state, or local. The church keeps an ongoing partnership with the Lottie Moon and similar causes through prayer and giving, and the missions spotlight has recently been the Semidey Sending Celebration, marking a family's family transition to overseas service. Anyone sensing their own can write to pastor@windsorcornerstone.org.
Operation Christmas Child is one of the church's most visible hands-on mission points. Throughout the year, the church family collects specific items for shoeboxes, toothbrushes in April, combs and brushes in May, water bottles and washcloths in June, school supplies in July, filler items in August, and monetary gifts in September. The year culminates in a giant packing party where the boxes are prepared together.
Worship Team, Giving, and Getting Connected
The worship ministry invites instrumentalists and singers to join the team, with Jarrett Slusher overseeing auditions and rehearsals. A copy of the worship handbook is available online.
Cornerstone's ministry is funded by the tithes and offerings of its members, attenders, and friends. Online giving is available through a secure server, and the giving page lays out four reasons the church recommends it: personal spiritual growth through first-fruits faithfulness, supporting the church's ministry, simplicity for travelers, and security for the gift itself.
First-time visitors can plan their visit through the New to Cornerstone page, which explains what a service is like, describes the children's ministry, names the Bible translations used in preaching, and answers the recurring question about the pastor's bare feet. The church office is open Monday through Friday from 9:00 a.m. to 1:00 p.m., and the team can be reached at office@windsorcornerstone.org or 970-686-7214. Anyone who prays the prayer of salvation on the How Can I Be Saved? page and wants to talk with someone about their decision is invited to call Pastor Tree at the church office number.
