So, you have three possibilities in world missions. You can be a goer, a sender, or disobedient. The Bible does not assume that everyone goes. But it does assume that the ones who do not go care about goers and support goers and pray for goers and hold the rope of the goers.
John PiperChrist did not die to forgive sinners who go on treasuring anything above seeing and savoring God. And people who would be happy in heaven if Christ were not there, will not be there. The gospel is not a way to get people to heaven; it is a way to get people to God. It's a way of overcoming every obstacle to everlasting joy in God. If we don't want God above all things, we have not been converted by the gospel.
John PiperThe vast majority of abortions are performed between the seventh and tenth week when the baby is already sucking his thumb, recoiling from pricking, responding to sound. All his organs are present, the brain is functioning, the heart is pumping, the liver is making blood cells, the kidneys are cleaning fluids, and there is a fingerprint. His genetic code is uniquely and unquestionably human. And, if we are willing, he can be seen by ultrasound.
