Galatians 4:4-7

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

that those under law he may redeem, that the adoption of sons we may receive;

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.
