Gee why didn't God think of that, oh wait, He did.
Jas:2:14:
What doth it profit,
my brethren,
though a man say he hath faith,
and have not works?
can faith save him?
Jas:2:15:
If a brother or sister be naked,
and destitute of daily food,
Jas:2:16:
And one of you say unto them,
Depart in peace,
be ye warmed and filled;
notwithstanding ye give them not those things which are needful to the body;
what doth it profit?
Jas:2:17:
Even so faith,
if it hath not works,
is dead, being alone.
Jas:2:18:
Yea,
a man may say,
Thou hast faith,
and I have works:
shew me thy faith without thy works,
and I will shew thee my faith by my works.
