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 PiperNot going to God because your faith is weak is like not going to the doctor because you feel sick.
John PiperChristianity is fundamentally convalescence.. .God is not only the doctor who prescribes, He is the nurse who lifts up our powerless head and puts the spoon in our mouth...And He is the medicine.
John PiperThat's who Jesus Christ is. He became the final Priest and the final Sacrifice. Sinless, he did not offer sacrifices for himself. Immortal, he never has to be replaced. Human, he could bear human sins. Therefore he did not offer sacrifices for himself; he offered himself as the final sacrifice. There will never be the need for another. There is one mediator between us and God. One priest. We need no other. Oh, how happy are those who draw near to God through Christ alone.
