The hardest commandment ever given to man is a commandment given to men. In Ephesians 5, men are instructed to love their wives “as Christ loves the church”. The disunity in marriages is a primary reason for the disparity and suffering in the world, and even in Christian fellowships. As men, we have often failed this commandment to love radically, and so we have failed to be a picture of the world of Christ and His Bride.
This is the hardest commandment, and this is how to love as Yeshua loved.
