We are born again by the incorruptible seed, by the Word of God itself. Incorruptible means that is does not perish or decay. When we become a child of God, new life begins in us, eternal life. And that ye put on the new man, which after God is created in righteousness and true holiness. We are to love one another because our flesh withers and falls away ever so quickly.
Life is ever so short.
It lasts no longer than the grass that appears so quickly and then withers away of the flower that appears just as quickly and falls away. People work and work to be glorious, to be attractive, acceptable, honorable, upstanding, recognized, charming, appealing, esteemed, dignified, and beautiful. But no matter how much glory man achieves, he ages, wrinkles, deteriorates, and passes off the scene. The voice said, Cry. My days are swifter than a weaver's shuttle, and are spent without hope.
