"The greatest obstacle to evangelization is superficial preaching." --Pope John Paul II
[2 Timothy 3:16-4:5]
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works.
I charge thee therefore before God, and the Lord Jesus Christ, who shall judge the quick and the dead at his appearing and his kingdom; 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.
But watch thou in all things, endure afflictions, do the work of an evangelist, make full proof of thy ministry.
[Luke 21:33] Heaven and earth shall pass away: but my words shall not pass away.
[Matthew 28:19-20] Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world.
