John 3:16 For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
My first memory of this verse was learning it for confirmation classes when I was young; but the real treasure held in the verse only came to me when I was a few years older.
This is God’s one and only Son who was willingly given for us; that is how much God loves us and cares for us.
Being willing to give your own life for others is something easier said than done. Jesus had time to sit and think about what He was doing; it was not a spur of the moment reaction.
