From A.W. Tozer’s book, God Tells the Man Who Cares, his entry entitled “The Vital Place of the Church”:
The highest expression of the will of God in this age is the church which He purchased with His own blood. To be scripturally valid any religious activity must be part of the church. Let it be clearly stated that there can be no service acceptable to God in this age that does not center in and spring out of the church. Bible schools, tract societies, Christian business men’s committees, seminaries, and the many independent groups working at one or another phase of religion need to check themselves reverently and courageously, for they have no true spiritual significance outside of or apart from the church.
According to the Scriptures the church is the habitation of God through the Spirit, and as such is the most important organism beneath the sun. She is not one more good institution along with the home, the state, and the school; she is the most vital of all institutions-the only one that can claim a heavenly origin.
The cynic may inquire which church we mean, and may remind us that the Christian church is so divided that it is impossible to tell which is the true one, even if such a one exists. But we are not too much troubled by the suppressed smile of the doubter. Being inside the church we are probably as well aware of her faults as any person on the outside could possibly be. And we believe in her nevertheless wherever she manifests herself in a world of darkness and unbelief.
The church is found wherever the Holy Spirit has drawn together a few persons who trust Christ for their salvation, worship God in spirit and have no dealings with the world and the flesh. The members may by necessity be scattered over the surface of the earth and separated by distance and circumstances, but in every true member of the church is the homing instinct and the longing of the sheep for the fold and the shepherd. Give a few real Christians half a chance and they will get together and organize and plan regular meetings for prayer and worship. In these meetings they will hear the Scriptures expounded, break bread together in one form or another according to their light, and try as far as possible to spread the saving gospel to the lost world.
Such groups are cells in the Body of Christ, and each one is a true church, a real part of the greater church. It is in and through these cells that the Spirit does His work on earth. Whoever scorns the local church scorns the Body of Christ. *
The church is still to be reckoned with. “The gates of hell shall not prevail against her.”
