18 For there is a revelation of the wrath of God from heaven against all the wrongdoing and evil thoughts of men who keep down what is true by wrongdoing;
19 Because the knowledge of God may be seen in them, God having made it clear to them. 20 For from the first making of the world, those things of God which the eye is unable to see, that is, his eternal power and existence, are fully made clear, he having given the knowledge of them through the things which he has made, so that men have no reason for wrongdoing: 21 Because, having the knowledge of God, they did not give glory to God as God, and did not give praise, but their minds were full of foolish things, and their hearts, being without sense, were made dark. 22 Seeming to be wise, they were in fact foolish, 23 And by them the glory of the eternal God was changed and made into the image of man who is not eternal, and of birds and beasts and things which go on the earth. 24 For this reason God gave them up to the evil desires of their hearts, working shame in their bodies with one another: 25 Because by them the true word of God was changed into that which is false, and they gave worship and honour to the thing which is made, and not to him who made it, to whom be blessing for ever. So be it.

Commentary on Romans 1:18-25
(Read Romans 1:18-25)
The apostle begins to show that all mankind need the salvation of the gospel, because none could obtain the favour of God, or escape his wrath by their own works. For no man can plead that he has fulfilled all his obligations to God and to his neighbour; nor can any truly say that he has fully acted up to the light afforded him. The sinfulness of man is described as ungodliness against the laws of the first table, and unrighteousness against those of the second. The cause of that sinfulness is holding the truth in unrighteousness. All, more or less, do what they know to be wrong, and omit what they know to be right, so that the plea of ignorance cannot be allowed from any. Our Creator's invisible power and Godhead are so clearly shown in the works he has made, that even idolaters and wicked Gentiles are left without excuse. They foolishly followed idolatry; and rational creatures changed the worship of the glorious Creator, for that of brutes, reptiles, and senseless images. They wandered from God, till all traces of true religion must have been lost, had not the revelation of the gospel prevented it. For whatever may be pretended, as to the sufficiency of man's reason to discover Divine truth and moral obligation, or to govern the practice aright, facts cannot be denied. And these plainly show that men have dishonoured God by the most absurd idolatries and superstitions; and have degraded themselves by the vilest affections and most abominable deeds.
