Paul writes in Ephesians 3:16: "I pray that from His glorious, unlimited resources He will give you mighty inner strength through His Holy Spirit."
That's my desire. To tap into His glorious, unlimited resources so I can accomplish what He has for me to do. I sure can't do it on my own. When I wrote books under my own power (during my pre-CBA career), I definitely used the talent God gave me, but I didn't write the books He wanted me to write. Now, if I hope to use the talent for God's purposes, I have to have His power to go with it or I am lost.
Florence Nightingale said: "Life is a hard fight, a struggle, a wrestling with the principle of evil, hand to hand, foot to foot. Every inch of the way is disputed. The night is given us to take breath and to pray, to drink deep at the fountain of power. The day, to use the strength that has been given us, to go forth to work with it till the evening."
God doesn't ask us to walk in our own strength. If Jesus is our Lord, we can walk in *His* strength. That's a good reminder for all of us.
