Romans 8:14-16 King James Version (KJV)
14 For as many as are led by the Spirit of God, they are the sons of God.
15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
16 The Spirit itself beareth witness with our spirit, that we are the children of God:
Romans 8:14-16 Amplified Bible (AMP)
14 For all who are allowing themselves to be led by the Spirit of God are sons of God. 15 For you have not received a spirit of slavery leading again to fear [of God’s judgment], but you have received the Spirit of adoption as sons [the Spirit producing sonship] by which we [joyfully] cry, “[a]Abba! Father!” 16 The Spirit Himself testifies and confirms together with our spirit [assuring us] that we [believers] are children of God.
