Self-sufficiency is Satan’s net, wherein he catches men, like poor silly fish, and does destroy them. Be not self-sufficient. Think yourselves nothing, for you are nothing, and live by God’s help. The way to grow strong in Christ is to become weak in yourself. God pours no power into man’s heart till man’s power is all poured out. Live, then, daily, a life of dependence on the grace of God. Do not set yourself up as if you want an independent gentleman; do not start in your own concerns as if you could do all things yourself; but live always trusting in God. You have as much need to trust Him now as ever you have; for, mark this, although you would have been damned without Christ, at first, you will be damned without Christ now, unless He still keeps you.
C.H. Spurgeon
