There are only three kinds of Christians when it comes to world missions: zealous goers, zealous senders, and disobedient.
John PiperObedience does not consist in paying God back and thus turning grace into a trade. Obedience comes from trusting in God for more grace - future grace - and thus magnifying the infinite resources of God's love and power.
John PiperThe offspring of the woman, Jesus Christ, came into the world to save women who have dethroned God, taken His place, defined personhood as tissue, and willed the death of their own child. It can't be reversed, but it can be forgiven. That is why Christ died.
John PiperThe really wonderful moments of joy in this world are not the moments of self-satisfaction, but self-forgetfulness. Standing on the edge of the Grand Canyon and contemplating your own greatness is pathological. At such moments we are made for a magnificent joy that comes from outside ourselves.
