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. Professing themselves to be wise, they became fools, And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things. Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves: Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
God is obvious. His truth is obvious. The account of Scripture puts everything into place, and it makes sense. It is consistent. It goes together. It defines our world and our lives. God is the originator and the creator of everything that exists, and He rules over all in supreme authority. But sin rejects that and distorts it. Pride rejects that, and so man tries to change it. Sinful man takes everything good that God gave and that God does and twists it to satisfy himself while leaving God out of it.
Our beliefs affect our behavior. Paul describes a process where people got some wrong ideas in their heads. When they saw the unmistakable evidence of God, they didn’t view Him as He is, but how they imagined Him to be. They made their own gods. They made themselves gods, essentially, becoming creators instead of creatures, failing to recognize their place far below a holy, all-knowing, all powerful God.
As a result, they do things God would not approve of. They change worship and what it should be, and when God is not the object of worship, other things become corrupted, too. This leads to all the sins that Paul lists, every form of unrighteousness that goes against God and His established way of righteousness, everything that glorifies self and corrupts relationships and family and godly authority and godly ways until the exact opposite is what becomes acceptable to them.
Living without proper regard for God leads to all kinds of wrong things. And if we aren’t careful, it can happen to believers just as easily as unbelievers. Many today are trying to change the truth of God to suit themselves, and sadly, some Christians are even being swept away by those attitudes. But leaving God out of any part of our lives is a slippery path to take. So may we seek to give God a place of preeminence in our lives and let nothing else steal His glory. May He be at the center of our worship. And may we forsake our sin and seek to do only those things that please Him.
