Wherefore God also gave them up to uncleanness
Not by 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 given up
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.
