There is a clear distinction between the children of God and the children of the Devil. God’s children hear His voice and obey Him. The children of the Devil do not listen to God’s voice; they disobey Him by doing the will of their father, Satan. There are only two families, and everyone belongs to one or the other. Both groups have one thing in common, however. The members of each family do the will of their respective fathers, whether God or Satan.
