There is no fear in love, but perfect love drives out fear because fear has to do with punishment, and so one who fears is not yet perfect in love.
1 John 4:18
Hunger for love and unity
Beloved, let us love one another, because love is of God; everyone who loves is begotten by God and knows God. Whoever is without love does not know God, for God is love. 1 John 4:7-8
How You can walk in the Spirit?
Beloved, do not trust every spirit but test the spirits to see whether they belong to God, because many false prophets have gone out into the world. This is how you can know the Spirit of God: every spirit that acknowledges Jesus Christ come in the flesh belongs to God, and every spirit that does not acknowledge Jesus does not belong to God. This is the spirit of the antichrist that, as you heard, is to come, but in fact is already in the world. You belong to God, children, and you have conquered them, for the one who is in you is greater than the one who is in the world. They belong to the world; accordingly, their teaching belongs to the world, and the world listens to them. We belong to God, and anyone who knows God listens to us, while anyone who does not belong to God refuses to hear us. This is how we know the spirit of truth and the spirit of deceit. 1 John 4:1-6
Give Him your whole self
They were overjoyed at seeing the star, and on entering the house they saw the child with Mary his mother. They prostrated themselves and did him homage. Then they opened their treasures and offered him gifts of gold, frankincense, and myrrh. Matthew 2:10-11
God's children
Children, let no one deceive you. The person who acts in righteousness is righteous, just as he is righteous. Whoever sins belongs to the devil, because the devil has sinned from the beginning. Indeed, the Son of God was revealed to destroy the works of the devil. No one who is begotten by God commits sin, because God’s seed remains in him; he cannot sin because he is begotten by God. In this way, the children of God and the children of the devil are made plain; no one who fails to act in righteousness belongs to God, nor anyone who does not love his brother. 1 John 3:7-10
