Romans 8:9-11, 14

However, you are not in the flesh but in the Ruach—if indeed the Ruach Elohim dwells in you. Now if anyone does not have the Ruach of Messiah, he does not belong to Him. But if Messiah is in you, though the body is dead because of sin, yet the Spirit is alive because of righteousness. And if the Ruach of the One who raised Yeshua from the dead dwells in you, the One who raised Messiah Yeshua from the dead will also give life to your mortal bodies through His Ruach who dwells in you.

For all who are led by the Ruach Elohim, these are sons of God.
