But whatever you do, find the God-centered, Christ-exalting, Bible-saturated passion of your life, and find your way to say it and live for it and die for it. And you will make a difference that lasts. You will not waste your life.
John PiperThe Bible is the ultimate authority and infallible, not the pastor and not the elders. And it doesn't mean that you believe everything he says without examining it.
John PiperThe key to praying with power is to become the kind of persons who do not use God for our ends but are utterly devoted to being used for His ends.
