God Is There
Advent 2024
December 15, 2024
Rev. Dr. Gabe Sylvia

Using the Gateway Arch and Revelation 3:7, the sermon reassures a struggling church that God’s omniscience and sovereign authority—He knows our works, our enemy, and our end, and alone holds the keys to open and shut doors—guarantee the church’s identity, ministry fruitfulness, and believer’s assurance.
Summary
Starting with the image of St. Louis as a gateway, the sermon turns to Revelation 3:7 and the letter to the church at Philadelphia to encourage a struggling congregation about identity and mission. It emphasizes God’s omniscience—His exhaustive, immediate knowledge of all things (illustrated with Psalm 139)—including our works, our enemies, and our final destiny. Because Christ alone holds the keys, when He opens a door no one can close, and believers can be assured that condemnation is removed and true fruit will endure. The message calls for sincere (not perfect) obedience, repentance, reliance on God’s power in ministry openings, and participation in communal practices like prayer and the Lord’s Supper.
