The 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 PiperAdjust your doctrine - or just minimize doctrine - to attract the world, and in the very process of attracting them, lose the radical truth that alone can set them free.
John PiperDon't wait for a feeling or love in order to share Christ with a stranger. You already love your heavenly Father, and you know that this stranger is created by Him, but separated from Him... so take those first steps in evangelism because you love God. It is not primarily out of compassion for humanity that we share our faith or pray for the lost; it is first of all, love for God.
John PiperIf God were not just, there would be no demand for his Son to suffer and die. And if God were not loving, there would be no willingness for his Son to suffer and die. But God is both just and loving. Therefore his love is willing to meet the demands of his justice.
