whom God displayed publicly as a propitiation in His blood through faith. This was to demonstrate His righteousness, because in God’s merciful restraint He let the sins previously committed go unpunished;

Therefore, in all things He had to be made like His brothers 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 the sins 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.
