“Do not waste time bothering whether you ʿloveʾ your neighbour; act as if you did. As soon as we do this we find one of the great secrets. When you are behaving as if you loved someone, you will presently come to love him.”
~ Mere Christianity (emphasis mine)
Make no bones about it, Love is an act of the will. Willing the good of the other as other.
Much of the time its easy to align our wills with our emotions or senses and love. Still even when there is no other reason pointing you toward love, you can will it actively. You could make the case then that Jesus’s most willful act (and therefore most loving), because it is a pure act of the will, is allowing himself to hang on the cross and be killed.
Think about that.
