Whatever we do for us in selfishness dies with us without impacting anyone, bringing NO glory to GOD whereas whatever we do for GOD/others; like sharing Gospel/JESUS, delivers people in darkness from the clutches of Satan from their fears, tears, pains, hopelessness and helping the poor and needy becomes Immortal, gets into GOD's books, qualifying us for eternal rewards and treasures. [Proverbs 11.30], [John 6.27],[Mark 10.29-30],[Matthew 6.19-20]. Remember though life on earth is temporary and short it is the only opportunity we have to decide Where and How we will spend our eternity; in Heaven with Rewards, Treasures or in hell with pains, tears! Wake up, work towards it. Be wise.
