Hi Izzy. There are indeed some verses in the
Bible that indicate God does not change. Here are just a few:
Malachi 3:6 "I the LORD do not
change. So you, O descendants of Jacob, are not
James 1:17 "Every good and perfect gift is from
above, coming down from the Father of the heavenly lights, who does not
change like shifting shadows."
Hebrews 13:8 "Jesus Christ
is the same yesterday and today and forever."
There are several others as well. I'm
wondering if your friend might be LDS. It's typically the LDS who raise
this question. If that's the case, there are several verses in the Book of
Mormon that say that God has never changed, but has always been God. Now
we do not believe the Book of Mormon to be Scripture, but this is a clear
biblical teaching found in the book of Mormon that is contradicted in official
LDS doctrine. If your friend is LDS, and you'd like those quotes as well,
let us know. God bless!
