'Essential' in the Bible

Therefore, it was essential that He had to be made like His brothers (mankind) in every respect, so that He might [by experience] become a merciful and faithful High Priest in things related to God, to make atonement (propitiation) for the people’s sins [thereby wiping away the sin, satisfying divine justice, and providing a way of reconciliation between God and mankind].

For every high priest is appointed to offer both gifts and sacrifices; so it is essential for this One also to have something to offer.
