For the word of God is quick, and powerful, and sharper than any two-edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
For you did not receive the spirit of bondage again to fear, but you received the Spirit of adoption by whom we cry out. “Abba. Farther”
The Spirit Himself bears witness with our spirit that we are children of God.
And if children, then heirs of God and joint heirs with Christ, if indeed we suffer with Him, that we may also be glorified together.
Likewise the Spirit also helps in our weaknesses. For we do not know what we should pray for as we ought, but the Spirit Himself makes intercession for us with groaning which cannot be uttered. Now He who searches the hearts knows what the mind of the Spirit is, because He makes intercession for the saints according to the will of God. And we know that all things work together for good to those who love God, to those who are the called according to His purpose.
