The central message of this sermon is that people often redefine God in their own image and likeness, seeking a deity that they can live with, rather than accepting the true nature of God as revealed in Scripture. This mindset is rooted in human nature's tendency to want to control and manipulate God to fit our own preferences and values. However, the Bible teaches that everyone already knows that God exists, but we turn from this knowledge and seek to redefine Him. The sermon argues that our role is not to try to convince others of God's existence through reason or evidence alone, but rather to shine light on God's character through our lives and words, allowing God to give sight to those who are blind to His truth. This balance between reason and revelation is key to effective apologetics, and the sermon emphasizes that we should not try to give people sight, but rather trust God to do so while we provide light for them to see. Ultimately, the sermon seeks to highlight the fundamental issue of human rebellion against God's sovereignty, rather than simply debating whether or not He exists.
