"And as ye go, preach, saying, The kingdom of heaven is at hand."
"And how shall they preach, except they be sent? as it is written,
How beautiful are the feet of them that preach the gospel of peace,
and bring good tidings of good things!"
"For the preaching of the cross is to them that perish foolishness;
but unto us which are saved it is the power of God."
1 Corinthians 1:18
"For we preach not ourselves, but Christ Jesus the Lord;
and ourselves your servants for Jesus' sake."
2 Corinthians 4:5
"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 will 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."
2 Timothy 4:1-5
"And Jesus came and spake unto them, saying, All power is given unto me
in heaven and in earth. 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. Amen."
