The Lord added then, the Lord changes not, the Lord adds now. If a church ain't growing, there's a problem, of some kind... and it's not the Lord's fault, of that you can be very sure
If a Church is not growing it may be because it is telling the truth,
Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine, for the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers having itching ears, and they shall turn away their ears from the truth and shall be turned unto fables (2Tim.4:2-4)
