Romans 1:
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:
21Because 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.
In vs 18, the words "who hold" are translated from the Greek word katechō which means to hold back, to restrain.
In vs 19, we see what it is that men restrain ... that which may be known of God ... for God showed it to them. God reveals Himself, His truth, and that truth, that revelation is suppressed and restrained. So it is mankind who restrains. It is not God Who withholds.
In vs 20, God's eternal power and Godhead is suppressed, restrained, rejected and that is why they are without excuse.
There is no excuse come judgment day.
