'Propitiation' in the Bible

whom God displayed publicly as a propitiation in His blood through faith. This was to demonstrate His righteousness, because in the forbearance of God He passed over the sins previously committed;

Therefore, He had to be made like His brethren in all things, so that He might become a merciful and faithful high priest in things pertaining to God, to make propitiation for the sins of the people.

and He Himself is the propitiation for our sins; and not for ours only, but also for those of the whole world.

In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins.
