"A new commandment I give to you, that you love one another,
even as I have love you, that you also love one another."
I will be the first to admit that sometimes I don't feel very loving, especially if I have been hurt by someone. Jesus knows our human nature and knows that is usually how we feel after being hurt and feeling justified in those feelings.
This is why He commands us to love one another, because it doesn't come naturally to us. Jesus knows His LOVE is the best buffer between hurt relationships if only we reach for His word to deal with our hurts and pain. God is not a God of "three strikes and you are out" kind of God. He has forgiven me endless times and keeps extending His mercy and love on me. My desire is to be more like Jesus.
What would this world look like if we were able to extend that kind of love and mercy to the hurting world around us?!
