Are all the numerous churches of the world qualified to receive the everlasting salvation? Those who worship God in vain by keeping the commandments of men cannot enter heaven.
Cain’s sacrifice (Vain sacrifice) = Worshiping God with rules of men.
Abel’s sacrifice (True sacrifice) = Worshiping God with commands of God.
In this age there is a great battle between God’s saints and Satan. We must lead people of the whole world to Zion where we can keep God’s commands.
