2 Corinthians 4:13-18 KJV We having the same spirit of faith, according as it is written, I believed, and therefore have I spoken; we also believe, and therefore speak; knowing that he which raised up the Lord Jesus shall raise up us also by Jesus, and shall present us with you. For all things are for your sakes, that the abundant grace might through the thanksgiving of many redound to the glory of God. For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day. For our light affliction, which is but for a moment, worketh for us a far more exceeding and eternal weight of glory; while we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.
This is a dark world, I remember hearing Dr. Myles Munroe mentioned in his teaching the darkness is ignorance. People who are in the world are ignorant; but we as believers are called to love those who are lost and share the true and good gospel to lost in the world.
