When you find yourself around a self-centered person, the easy thing to do is withhold love. Show them God’s love regardless. They may not want to experience that kind of love but give it nonetheless.
The act of compassion you do toward others may not be remembered by them but do it anyway. You will be vulnerable when you move in the way God moves but walk His way anyhow.
What you give away to others might not return to you in the form of a blessing but give abundantly notwithstanding. It makes you smell like God’s servant.
From the cross, we see true agape love. Luke 23:34 we read, 34 “Then said Jesus, Father, forgive them; for they know not what they do. And they parted his raiment, and cast lots.”
Just a few thoughts from me to you.
