To love God is to share God's nature and to love others

1 John 4:13-5:3
If anyone acknowledges that Jesus is the Son of God, God lives in them and they in God. 
And so we know and rely on the love God has for us. God is love. Whoever lives in love lives in God, and God in them.
There is no fear in love. But perfect love drives out fear, because fear has to do with punishment. The one who fears is not made perfect in love.
And he has given us this command: Anyone who loves God must also love their brother and sister.
Love and obedience are bound up together. If we love and obey God, we need not dread the day of judgment.
Father is what brings us into God's family .To love God is to share God's nature and to love others. Love for God makes obedience natural, not burdensome.
Why?
Because God is love, whoever lives in love lives in God, and God in them. This is the truth and do not fear the judgment.The one who fears is not made perfect in love, the conscience will accuse us.
There is no fear in love like a mother loves his child.
Love one another is sharing God's nature, so it is not burden but make obedience.
How?
To love God is to share God's nature and to love others, it is joy!
