And how can we be sure that we belong to him? By obeying his commandments.
If someone says, "I belong to God," but doesn't obey God's commandments, that person is a liar and does not live in the truth.
But those who obey God's word really do love him. That is the way to know whether or not we live in him.
Those who say they live in God should live their lives as Christ did.
