Self-sacrificial love is laying your love for that person down at the altar, knowing that they’re not yours to love, and hoping that God will use you to love them.
“God, I love this person. But I know that you love him so much more than I ever will and you can love him so much more sufficiently than I ever could. So, I’m giving my love for him up to you, because you can love him so much better than I can. I trust your ways of loving him more than I do my own. So please use me to fulfill your ways.” Amen.
