New Signature Series From Cross Communication: Thy Kingdom Come — Speaking Heaven Into Earth

In 2026, Heather is focused on training the Church to pray strategically, speak intentionally, and live as witnesses who carry heaven into everyday life. This series can be customized to your event in one, two, three, or all four sessions.

In this series, former communication Professor, Heather Thompson Day, equips the Church to understand its identity and authority in prayer. Beginning with what it means to be made in the image of God, she builds a biblical case for the creative power of God’s Word and the responsibility believers carry in their own words. Through practical teaching on how speech shapes our brains, relationships, and spiritual authority, audiences learn how to speak with intention and alignment. The series concludes by training believers to live as bold witnesses, carrying heaven into earth until God’s Kingdom becomes visible wherever they stand.

1. What Are We Doing Here?

What does it actually mean to be made in the image of God? In this message, Heather reframes identity not as self-expression, but as divine representation. Drawing from Genesis and the larger biblical narrative, she shows that image bearers were created with purpose, authority, and assignment. Audiences leave understanding that they are not here by accident, but commissioned to reflect God’s character in this world.

2. God Can Talk

From the opening words of Genesis to the ministry of Jesus, Scripture reveals a God who creates through speech. In this message, Heather explores the creative power of God’s Word and love, and contrasts this Creation story with the violent, distant gods of the ancient world. If God speaks and reality responds, then His Word is not symbolic, it is active. This talk builds faith in a God who still speaks, still moves, and still brings life through His voice.

3. Say It Yourself

If we are made in the image of a speaking God, what does that mean for our words? Combining biblical theology with communication research and brain science, Heather reveals how language shapes our relationships, our emotions, and even our neural pathways. This message challenges believers to stop speaking casually and start speaking strategically. When our words align with God’s truth, they do not just describe reality, they have authority on earth.

4. Until You Get There

Before miracles often came, someone spoke. In this closing message, Heather trains believers to live as witnesses who testify to what God has done and what He will do. Acts 1:8 says, "you shall be witnesses of me," but how many of us know what this means, or how to live it out? This talk equips audiences to carry hope into impossible spaces and to keep declaring God’s goodness until they see it with their own eyes.
