David Adams addresses the concept of absolutes in his sermon, emphasizing the importance of recognizing that truth is absolute despite contemporary beliefs that deny this notion. He highlights the significance of Jesus' declaration, 'Before Abraham was, I am,' as the ultimate absolute, affirming Christ's eternal existence and divine authority. Adams argues that while society may claim there are no absolutes, the very act of labeling something as a lie acknowledges an absolute truth. He encourages the congregation to understand the implications of believing in Jesus as the I AM, the changeless Lord of eternity, who remains the same throughout all ages.
