Isaiah 49:15 asks the most honest parenting question in the Old Testament: "Can a woman forget her sucking child, that she should not have compassion on the son of her womb?" The answer given is: even if she could, God cannot forget. The Hebrew word for "compassion" β racham β shares a root with rechem, the word for womb. God's attachment to the people who have wandered from him is described as the visceral, physical kind β not a sentiment but an instinct that cannot be switched off. The parent waiting for the prodigal child is participating in something God knows from the inside.
Jeremiah 31:20 records God speaking of the wayward Ephraim: "Is Ephraim my dear son? is he a pleasant child? for since I spake against him, I do earnestly remember him still: therefore my bowels are troubled for him; I will surely have mercy upon him, saith the LORD." The phrase "my bowels are troubled" is visceral β it is not polite feeling but the kind of grief that lives in the body. God describes his reaction to his wandering child in physical terms. The parent who aches physically for a prodigal child is in the company of God's own self-description.
