Why Believing in God Matters
Teachers
Lesson Summary
The class began by reflecting on the extensive series of lectures that had examined the evidence for God's existence, ranging from cosmological arguments to archaeological findings. After acknowledging the depth of those intellectual pursuits, Tim Lewis was invited to address the next vital question: why does believing in God matter? He described God as the source of purpose and meaning, asserting that without Him life would lack direction and value. By referencing Psalm 16:2, he expressed that apart from the Lord there is no good, and emphasized that believers are created in God's image, bought with Christ’s sacrifice, and called to glorify Him in every aspect of life. Tim connected biblical teachings to everyday purpose, citing 1 Corinthians 6:19‑20 to remind believers that their bodies are temples of the Holy Spirit, and Philippians 1:20 to encourage living in a way that magnifies Christ. He used metaphors of lenses to illustrate how Christians can make the distant Christ visible to a skeptical world. The session concluded with a call to edify one another (Romans 14:19; 1 Thessalonians 5:11), urging the congregation to live purposefully, support each other, and continually glorify God.
Key Scriptures
I said to the Lord, 'You are my Lord; apart from you I have no good thing.'
Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought with a price. So honor God with your bodies.
I hope that in nothing I will be ashamed, but that with all boldness, Christ will be magnified in my body—whether by life or by death.
