Romans 8:13

10 and if Christ [is] in you, the body, indeed, [is] dead because of sin, and the Spirit [is] life because of righteousness,

11 and if the Spirit of Him who did raise up Jesus out of the dead doth dwell in you, He who did raise up the Christ out of the dead shall quicken also your dying bodies, through His Spirit dwelling in you.

12 So, then, brethren, we are debtors, not to the flesh, to live according to the flesh;

13 for if according to the flesh ye do live, ye are about to die; and if, by the Spirit, the deeds of the body ye put to death, ye shall live;

14 for as many as are led by the Spirit of God, these are the sons of God;

15 for ye did not receive a spirit of bondage again for fear, but ye did receive a spirit of adoption in which we cry, `Abba -- Father.`

16 The Spirit himself doth testify with our spirit, that we are children of God;
