Children of God
1Behold what manner of love the Father has given to us, that we should be called children of God. And that is what we are! The reason  the world  does not know us is that  it did not know Him. 
2Beloved, we are now children of God, and what we will be has not yet been revealed. We know that when Christ appears, we will be like Him, for we will see Him as He is. 
3And everyone who has this  hope in Him purifies himself, just as Christ is pure.
4Everyone who practices  sin practices  lawlessness as well. Indeed,  sin is  lawlessness. 
5But you know that Christ appeared to take away  sins, and in Him there is no sin. 
6No one  who remains in Him keeps on sinning. No one  who continues to sin has seen Him or known Him. 
7Little children, let no one deceive you: The one who practices  righteousness is righteous, just as Christ is righteous. 
8The one who practices  sin is of the devil, because the devil has been sinning from the very start. This is why  the Son  of God was revealed, to destroy the works of the devil. 
9Anyone  born of  God  refuses to practice sin, because God’s seed abides in him;   he cannot go on sinning, because he has been born of  God. 
10By this the children  of God are distinguished  from the children of the devil: Anyone who  does not practice righteousness is not of  God, nor is anyone who  does not love his  brother.
Love One Another
(John 13:31-35; Romans 12:9-13)
11 This is the message  you have heard from the beginning:  We should love one another. 
12Do not be like Cain, who belonged to  the evil one and murdered his  brother. And why  did Cain slay him? Because his own deeds were evil, while those of his brother were righteous.
13So do not be surprised, brothers, if the world hates you. 
14We know that we have passed from  death to  life, because we love our brothers. The one who  does not love remains in  death. 
15Everyone who hates his  brother is a murderer, and you know that eternal life does not  reside in  a murderer. 
16By this we know what love is:  Jesus laid down His  life for us, and we ought to lay down our lives for our brothers. 
17 If anyone with  earthly  possessions  sees his  brother in need, but withholds his  compassion from him, how can the love  of God abide in him? 
18Little children, let us love not in word and  speech, but in action and truth. 
19And by this we will know that we belong to  the truth, and will assure our  hearts in His presence:  
20Even if our  hearts condemn us,   God is greater than  our hearts, and He knows all things. 
21Beloved, if our  hearts  do not condemn us, we have confidence before  God, 
22and we will receive from Him whatever  we ask, because we keep His  commandments and do what is pleasing in His sight. 
23And this is His  commandment: that we should believe in the name of His  Son, Jesus Christ, and we should love one another just as  He commanded us. 
24 Whoever keeps His  commandments remains in God, and God in him. And by this we know that He remains in us: by the Spirit  He has given us.
