In this message, guest speaker Dr. David Clark challenges us as believers to think critically about our faith, demonstrating that Christianity is not based on circular reasoning but is supported by clear thinking and evidence. He guides us through Psalm 19 to show how the natural world reveals God's existence and connects scientific discoveries, like the Big Bang, to reinforce the belief that the universe's beginning points to a divine cause. Dr. Clark strengthens our faith by encouraging us to embrace good reasoning and evidence as foundations for our belief in God.
