"And Jesus came and spoke to them, saying ‘All authority has been given to Me in heaven and on earth’ ” (Matthew 28:18).
For any enterprise to be successful, there must be an established and recognizable line of authority. Otherwise anarchy exists, and everyone makes up and follows his own set of rules.
The ultimate authority in religious matters is God, the Father; but He conveyed complete authority—in heaven and on earth—to His Son, Jesus Christ, who lays claim to such authority in this scripture.
Implicit conclusions from this scripture are that God had the right to convey His authority by His position as the Heavenly Father, that He gave Jesus this authority, and that there was a standard of behavior the Father had set in place.
Understanding these conclusions leads us to know beyond any doubt that every person who expects to receive the ultimate reward must submit to this established authority—in other words, we must obey the inspired word if we expect to go to heaven.
