'Son' in the Bible

was pleased to reveal his Son in me, that I may announce him as glad tidings among the nations, immediately I took not counsel with flesh and blood,

I am crucified with Christ, and no longer live, I, but Christ lives in me; but in that I now live in flesh, I live by faith, the faith of the Son of God, who has loved me and given himself for me.

but when the fulness of the time was come, God sent forth his Son, come of woman, come under law,

But because ye are sons, God has sent out the Spirit of his Son into our hearts, crying, Abba, Father.

So thou art no longer bondman, but son; but if son, heir also through God.

But what says the scripture? Cast out the maid servant and her son; for the son of the maid servant shall not inherit with the son of the free woman.
