Verses 18-19
"For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness, because that which is known about God is evident within them; for God made it evident to them."
God’s wrath has always been against men who hide the truth of God’s righteousness, and establish their own, which is nothing more than unrighteousness and ungodliness. The truth is, they know about God and His righteousness, because God has revealed Himself to all men, but they reject it.
Verse 20
"For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse."
Every since God created this world, all men have seen His power in the world around them, and they know He is God. They have no excuse to believe otherwise.
Verse 21
"For even though they knew God, they did not honor Him as God, or give thanks; but they became futile in their speculations, and their foolish heart was darkened."
Even though they know He is God, they refuse to acknowledge Him or be thankful. Because of this, all of their ideas and thoughts are meaningless. They can no longer think clearly.
Verses 22-23
"Professing to be wise, they became fools, and exchanged the glory of the incorruptible God for an image in the form of corruptible man and of birds and four-footed animals and crawling creatures."
Instead of acknowledging God, they choose to find meaning and purpose in the things He created. They have exchanged wisdom for foolishness.
Verse 24
"Therefore God gave them over in the lusts of their hearts to impurity, that their bodies might be dishonored among them."
God allowed them to seek after those things that filled their heart and in which they sought physical gratification, so that they would be despised and lose all respect for their bodies.
Verse 25
"For they exchanged the truth of God for a lie, and worshiped and served the creature rather than the Creator, who is blessed forever. Amen."
Romans 12 tells us that true worship is presenting ourselves to God. However, in order to please themselves they made a bad exchange. They choose to present their bodies to one another, and not to God.
Verses 26-27
"For this reason God gave them over to degrading passions; for their women exchanged the natural function for that which is unnatural, and in the same way also the men abandoned the natural function of the woman and burned in their desire toward one another, men with men committing indecent acts and receiving in their own persons the due penalty of their error."
Not all men and women did these things, but only those who progressed from bad to worse as the previous verses explained. Women chose to have sexual relations with women, and men chose to do the same with men. As a result they were disgraced and suffered the wrath of God in their flesh. Homosexuality is the natural progression and the
pinnacle of evil of a heart and mind that has rejected God.
Verse 28
"And just as they did not see fit to acknowledge God any longer, God gave them over to a depraved mind, to do those things which are not proper,"
"They" are those who have come to reject God and have shown the evidence of their rejection in their lust filled perversions. God allowed them to be ruled by their depravity, and "they" were filled with all unrighteousness doing those things that reveal just how evil they have become.
Verses 29-31
"...being filled with all unrighteousness, wickedness, greed, evil; full of envy, murder, strife, deceit, malice; they are gossips, slanderers, haters of God, insolent, arrogant, boastful, inventors of evil, disobedient to parents, without understanding, untrustworthy, unloving, unmerciful;"
There is no doubt that the world as a whole is guilty of these things (all have sinned), but the context of these verses is to show that the they are the result of man's rejection of God, and the culmination of that rejection is evidenced by those who participate in homosexual behavior. There is no doubt that all men are sinners, but Paul makes a point of showing that the wickedness of man is clearly seen in the behavior and the heart of those who practice homosexuality. It is the most grevious of behaviors, and every evil fills their hearts.
Verse 32
"...and, although they know the ordinance of God, that those who practice such things are worthy of death, they not only do the same, but also give hearty approval to those who practice them."
Again, the "they" in this verse is still speaking of those who are practicing homosexuals. The context never changed. Those homosexuals know full well that those who do such things as Paul listed are worthy of death, but it makes no difference to them, because they do not respect or acknowledge God in the least! They worship themselves, and they give hearty approval to anyone who will join them in their debauchery.
