1 John 2:3-5

3This is how we can be sure that we know God: If we obey God's commands, we know that we belong to him.

4Someone may say, ‘I belong to God.’ But if he does not obey God's commands, that person is telling a lie. He is not living in the way that God's true message teaches us.

5But anyone who obeys God's message shows that he really loves God completely. So this is how we know that we belong to God.
