When someone evolves in his own reasoning, and tries to claim Christian underpinnings, it’s a slippery slope. One must be very careful to acknowledge why the change in thinking is taking place. Is it the influence of culture or is it really about the truth of God?
Romans 1:18-32 18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; 19 Because that which may be known of God is manifest in them; for God hath shewed it unto them. 20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
The ‘invisible’ things can be seen through what God has created. We have the Bible in the senses realm to verify God and we also have the creation to some extent that can teach us about God.You can look at a tree and see what He’s about. You can look at the human body and see what He’s about. Man is not smarter than God and God clearly has made Himself know in a number of ways. There are no excuses.
21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. 22 Professing themselves to be wise, they became fools,
Man however can get caught up in the web of his own thinking and push back against God in a variety of ways, none of which necessarily contribute to true happiness. Yet God has allowed free choice rather than compulsion for man’s options. Every human being has a choice.
