2 Corinthians 5:7 (NKJV)
7 For we walk by faith, not by sight.
Romans 8:26-29New King James Version (NKJV)
26 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[a] with groanings which cannot be uttered. 27 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.
28 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. 29 For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren.
