In Christianity, the Great Commission is the instruction of the resurrected Jesus Christ to his disciples that they spread his teachings to all the nations of the world.
The commission was given first to the eleven apostles and later to Paul.
The eleven apostles
Matthew 28:16 Then the eleven disciples went away into Galilee, into a mountain where Jesus had appointed them. 17 And when they saw him, they worshipped him: but some doubted. 18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. 19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit: 20 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.
Mark 13:9 But take heed to yourselves: for they shall deliver you up to councils; and in the synagogues ye shall be beaten: and ye shall be brought before rulers and kings for my sake, for a testimony against them. 10 And the gospel must first be published among all nations. 11 But when they shall lead you, and deliver you up, take no thought beforehand what ye shall speak, neither do ye premeditate: but whatsoever shall be given you in that hour, that speak ye: for it is not ye that speak, but the Holy Spirit.
Mark 16:14 Afterward he appeared unto the eleven as they sat at meat, and upbraided them with their unbelief and hardness of heart, because they believed not them which had seen him after he was risen. 15 And he said unto them, Go ye into all the world, and preach the gospel to every creature. 16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
Mark 16:19 So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God. 20 And they went forth, and preached every where, the Lord working with them, and confirming the word with signs following. Amen.
Luke 24:45 Then opened he their understanding, that they might understand the scriptures, 46 And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: 47 And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem. 48 And ye are witnesses of these things. 49 And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high.
John 20:19 Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you. 20 And when he had so said, he shewed unto them his hands and his side. Then were the disciples glad, when they saw the Lord. 21 Then said Jesus to them again, Peace be unto you: as my Father hath sent me, even so send I you.
Acts 1:8 But ye shall receive power, after that the Holy Spirit is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
Acts 4:33 And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all.
Acts 10:40 Him God raised up the third day, and shewed him openly; 41 Not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with him after he rose from the dead. 42 And he commanded us to preach unto the people, and to testify that it is he which was ordained of God to be the Judge of quick and dead. 43 To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.
Hebrews 2:3 How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard him; 4 God also bearing them witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Spirit, according to his own will?
Acts 9:15 But the Lord said unto him, Go thy way: for he is a chosen vessel unto me, to bear my name before the Gentiles, and kings, and the children of Israel:
Acts 22:15 For thou shalt be his witness unto all men of what thou hast seen and heard.
Acts 22:21 And he said unto me, Depart: for I will send thee far hence unto the Gentiles.
Acts 23:11 And the night following the Lord stood by him, and said, Be of good cheer, Paul: for as thou hast testified of me in Jerusalem, so must thou bear witness also at Rome.
Acts 26:16 But rise, and stand upon thy feet: for I have appeared unto thee for this purpose, to make thee a minister and a witness both of these things which thou hast seen, and of those things in the which I will appear unto thee;
Romans 16:25 Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began, 26 But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:
Ephesians 3:1 For this cause I Paul, the prisoner of Jesus Christ for you Gentiles, 2 If ye have heard of the dispensation of the grace of God which is given me to you-ward: 3 How that by revelation he made known unto me the mystery; (as I wrote afore in few words, 4 Whereby, when ye read, ye may understand my knowledge in the mystery of Christ) 5 Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit; 6 That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel: 7 Whereof I was made a minister, according to the gift of the grace of God given unto me by the effectual working of his power. 8 Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ;
I hope you find this helpful.
