When you are deeply peaceful and confident that, because of Christ, God will bring you safely to his eternal kingdom and be the all-satisfying Treasure of your life forever, then you are free to see the truth, and love the truth, and speak the truth no matter what, and joyfully spread a passion for the truth whose name is Jesus.
John PiperThe missionary question is not, 'Where are there unbelievers?' and then send a missionary there. There are unbelievers everywhere! The missionary question is, 'Where are there people's who don't have any Christians in them or don't have a church strong enough to do the neighbor evangelism that we can do if we just want to do it?' That's the missionary question.
John PiperIf you alter or obscure the Biblical portrait of God in order to attract converts, you don't get converts to God, you get converts to an illusion. This is not evangelism, but deception.
John PiperOur obedience is God's pleasure when it proves that God is our treasure. This is good news, because it means very simply that the command to obey is the command to be happy in God. The commandments of God are only as hard to obey as the promises of God are hard to believe. The Word of God is only as hard to obey as the beauty of God is hard to cherish.
John Piper
