How to pick a Church by Dr. E.W. Bullinger
You ask, Where you are to worship?
We reply wherever God is glorified, Christ is exalted, God's Word is honored, the Holy Spirit's power is evidenced
and man abased. Never go anywhere where you do not know more of God's Word than when you entered. Never be in any Body
where you may be turned out; or have your name down where it may be scratched out. Be content with the membership which
God has given you in the spiritual unity of the Body of Christ, from which no power in Earth or Hell can cut you off and be
content that your name was written in the Lamb's book of life before the foundation of the world, and from which no power
in Earth or Hell can ever take it out. Do nothing to imply that you do not hold these priceless privileges to be of infinite
value; or that they can be added to in the slightest degree by any of man's corporate unities.
