“And Abraham ran unto the herd, and fetcht a calf tender and good, and gave it unto a young man; and he hasted to dress it. 8And he took butter, and milk, and the calf which he had dressed, and set it before them; and he stood by them under the tree, and they did eat.” Gen. 18:7-8
Abraham did not order his servants to fetch the calf. When it comes to giving God your best, you can’t have anyone else do it for you. You have to go find the best calf, tender and good.
