(Romans 10:14-15): "How can one hear without one who preaches? And how shall he preach unless they are sent?"

(1 Tim. 1:1): "Paul, an apostle of Jesus Christ, according to the command of God our Saviour, and the Lord Jesus Christ our hope."

Chapter 4. He who is called to preach the Gospel must immediately obey, and not postpone this work.

(Luke 9:59-60): "And he said to another, Follow me. He said: Lord! let me go first and bury my father. But Jesus said to him, "Let the dead bury their dead, and you go and preach the Kingdom of God."

(Galatians 1:15-17): "When God, who chose me from my mother's womb and called me by His grace, was pleased to reveal His Son in me, that I might preach His gospel to the Gentiles, I did not immediately consult with flesh and blood, nor did I go to Jerusalem to the Apostles who preceded me, but went to Arabia, and returned again to Damascus."

Chapter 5. You should not teach otherwise.

(John 10:1-2): "Verily, verily, I say unto you, Whoever does not enter the sheepfold by the door, but climbs over the other, is a thief and a robber; but he who enters by the door is a shepherd to the sheep." And a little lower

(John 10:7-8): "I am the door of the sheep. All of them, however many have come before Me, are thieves and robbers; but the sheep did not listen to them."

(Galatians 1:8-9): "But if we, or an angel from heaven, should preach to you any other gospel than that which we have preached to you, let him be accursed. As we said before, so now I say again: whoever preaches to you other gospel than that which you have received, let him be anathema."

(1 Timothy 6:3-4): "Whoever teaches otherwise, and does not follow the sound words of our Lord Jesus Christ, and the teaching of godliness, is proud, and knows nothing," and so on.
