"The first duty of love is to listen"—Paul Tillich
If I love someone I will listen to them. If I love God, I will listen to God. If I love my spouse, I will listen to my spouse.
To listen—truly listen—I must pay attention to them. For that moment I must put aside myself, my own thoughts, my own worries. I must focus on their words and not the words jangling around in my head.
If I listen closely enough, I might even hear God's whisper.
