When a well-known and anointed prophet turns up at home, not one of the household members even considered him worthy enough to be introduced. In every way, David was at the bottom.
Bring the brothers, food. Save the sheep and himself from the lions and the bears. And, no one to bother if he came out dead or alive. Yet! Why did David step up to fight Goliath? There was something that solidified his faith and confidence.
Even if my father and mother reject me, the Lord will hold me close – Psalm 27:10
David heard from God’s heart beat. The words that said, “You are my beloved Son”. From the core of God’s acceptance, David faced the giant. Not so that he could be accepted by his household, but fully being assured that He was accepted unconditionally by His Father in Heaven. David saw in God a Mum, a Dad, a Brother, a Sister, a Friend and a Lover who held him close.
