“I tell you for certain that a grain of wheat that falls on the ground will never be more than one grain unless it dies. But if it dies, it will produce lots of wheat. If you love your life, you will lose it. If you give it up in this world, you will be given eternal life. If you serve me, you must go with me. My servants will be with me wherever I am. If you serve me, my Father will honor you.”John 12:24-26 CEV
If you live selflessly to serve Jesus and follow Him, you will reap a reward and your life will benefit others.
If you live selfishly, all you do for yourself is all you will have for yourself when you come to the end of your self.
