1 John 4:20-1 John 5:5 - Keeping God's Commands

20 if a man says he loves God, and yet hates his brother, he is a lyar: for he that does not love his brother, who is before his eyes, how can he love God who is invisible? 21 besides, 'tis a commandment we have receiv'd from him, that he who would love God, must love his brother also.

1 Whosoever believeth that Jesus is the Messiah, is born of God: and every one that loves the father, will likewise be affected with love to his son. 2 by this we may know that we love the children of God, if we love God, and keep his commandments. 3 for our love of God consists in the observation of his precepts: precepts that are far from being grievous. 4 for he that is a true christian, overcomes the world: by obtaining faith, we have gain'd a victory over the world. 5 Who is it that overcomes the world, but he that believes that Jesus is the son of God?
