The mission of the church is missions.
Our work is to preach the gospel and we must not be sidetracked.
The Lord did not tell us to build beautiful churches, but to evangelize the world
If God wills the evangelization of the world, and you refuse to support missions, then you are opposed to the will of God.
Why should anyone hear the Gospel twice, before everyone has heard it once?
There can be no prevailing in prayer without travailing in prayer.
