Paul was an apostle, not a disciple. No offense there. However, I, too, am very thankful he preached to the gentiles, even though I'm a halfer.....a samaritan. Paul was chosen by God to write so much of the New Testament. Paul was a very honorable man, on fire for Jesus, and spoke what he was told by God. How can you not admire him. BUT, as I listed, I identify with Peter. His flesh would ooze out and Jesus told him that 'on this rock I will build my church.' Now Jesus isn't going to build a church on me, trust me, but this lets me know that I can aspire to be so much more than what I am today. "I can do all things through Christ who strengthens me." We're working on it.
If we look at it in direct teaching from Jesus to disciple then IMO: we open the door to many people that followed Jesus and were taught by him but if we look at what is being said by others we see only 12 talked about in the Bible and preached by many.
After Jesus death, Jesus appeared to 11 of the 12 disciple and said
Matthew Chapter 28
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 Ghost:
20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.
We also know that Jesus appeared to Paul on the road, who's to say he wasn't told to do the same as the 11 disciple were, especially since he did exactly what Jesus told the other disciple to do. I'll also submit to you God the Father and God the Son and God the Holy Spirit are one. Was not Paul taught by God did not Paul do what God said to do. Is it possible Paul was a disciple of Jesus and if were being taught by the Holy Spirit are we also disciple's of Jesus.
Look at the Scriptures.
What Is A Disciple of Jesus Christ?
Jesus commanded His servants to "make disciples of all the nations". But what is a disciple? Have you ever asked yourself what it really means to be a disciple of Jesus Christ? What exactly would that involve?

Do you think that if Peter did nothing at all, that Jesus Church would not be built. Jesus command us all to make disciples of all the nations. Jesus died once for all man kind and there was no other way then His church to be built.
