'Son' in the Bible

to reveal His Son in me, that I might proclaim him good news among the nations, immediately I conferred not with flesh and blood,

with Christ I have been crucified, and live no more do I, and Christ doth live in me; and that which I now live in the flesh -- in the faith I live of the Son of God, who did love me and did give himself for me;

and when the fulness of time did come, God sent forth His Son, come of a woman, come under law,

and because ye are sons, God did send forth the spirit of His Son into your hearts, crying, 'Abba, Father!'

so that thou art no more a servant, but a son, and if a son, also an heir of God through Christ.

but what saith the Writing? 'Cast forth the maid-servant and her son, for the son of the maid-servant may not be heir with the son of the free-woman;'
