The New John Gill Exposition of the Entire BibleRomans 1:24
Wherefore God also gave them up to uncleanness…
putting any into them, but by leaving them to the pollution of their
nature; by withdrawing his providential restraints from them, and by
giving them up to judicial hardness:
through the lusts of their own hearts.
The heart of man is the
source of all wickedness; the lusts that dwell there are many, and
these tend to uncleanness of one sort or another: by it here is
meant particularly bodily uncleanness, since it is said they were
to dishonour their own bodies between themselves;
either alone, or
with others; so that as they changed the glory of God, and
dishonoured him, he left them to dishonour themselves by doing these
things which were reproachful and scandalous to human nature.
