Commentary of Charles Spurgeon, Adam Clarke & Matthew Henry
Wherefore God also gave them up to uncleanness through the 
lusts of
their own hearts, to dishonor their own bodies between themselves: Who changed the truth of God into a lie, and worshiped and served the
creature more than the Creator, who is blessed for ever. Amen.
Vs.24,25
God - gave them up, etc. - They had
filled up the measure of their iniquities, and God, by permitting them
to plunge into all manner of irregularities, thus, by one species of
sin, inflicted punishment on another.....
Q: By whom they were given up.
A: God gave them up, in a way of
righteous judgment, as the just punishment of their idolatry-taking off the
bridle of restraining grace-leaving them to themselves-letting them alone; 
Dishonor their own bodies - Probably alluding here to what is more openly expressed, Romans 1:26, Romans 1:27.
Between themselves - εν εαυτοις, Of themselves, of their own free accord; none inciting, none impelling.
Changed the truth of God into a lie - In the place of the true worship of God, they established idolatry.
God is not the author of sin,--for, though the greatest wickedness follow upon this giving up, the fault of
that is to be laid upon the sinner's wicked heart.
