Psalm 147:10-11
His pleasure is not in the strength of the horse, nor His delight in the legs of man; the LORD delights in those who fear Him, who put their hope in His unfailing love.
We put a lot of effort into trying to sharpen our skills or increase our strength. There is nothing wrong with doing that when it can be used to glorify God. But when we use our skills with no regard for God, they are worth little. It is our fear (reverence) and trust that God desires.
Human strength and human cleverness do not impress God. We may feel ourselves so strong, so capable, but something can happen in just an instant that can rob us of all that strength and capability. God loves those who fear Him and put their hope in His unfailing love. There’s just one response of the human heart to which God reaches out, it is the response of faith, of love and of commitment to Him. Don’t rely on your own ability, don’t rely on your own strength, they will fail you sooner or later, but put your trust in the unfailing love and faithfulness and the mercy of God. Put your hope in Him and He will not fail you.
