Sons of God.

Receive Jesus.

Become a son of God by Jesus given power.

Believe on Jesus' name.

Be born by the will of God.

Joh 1:12  But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: 

Joh 1:13  Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. 

God said to Satan, Adam and Eve, to all their descendants-

Gen 3:15  And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel. 

I will put a hatred between you (Satan) and the woman.

I will put a hatred between your seed (Satan) and the seed of the woman.

The seed of the woman will bruise your head.

You will bruise the heel of the woman's seed.

Satan would use his own seed to bruise the heal of the woman's seed.

Satan's seed are those who walk after Satan's ways. In the very beginning Cain was Satan's. I'm not making this up.

1Jn_3:12  Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous.

The first child born to mankind chose Satan over God.  Cain was Satan's seed.

Those who crucified Christ were of Satan's seed. Christ - the seed of the woman defeated Satan, death could not hold Him. And through our risen Savior we are all able to become sons (daughters) of God.

All by HIS grace through HIS love we are given the power to be truly God's, seed of the woman (human birthed-God birthed-spiritual born).
