John 15:16 “Greater love has no one than this, that he lay down his life for his friends.”
Jesus displayed the greatest love in all of human history by literally laying down His life for His friends.that is you and I if we are born again.
Jesus died for us while we were still His enemies, still sinners, and hostile to the things of God (Rom 5).
You may not have to lay down your life in the sense of dying for others but laying down your life is investing time, talents, and treasure in esteeming others better than yourself (Phil 2:3).
Our life consists of only a short time on this earth and so when we lay down our lifetimes in serving others, we are laying down our time for others and we are no more like God than when we sacrifice what we want for what others need.
