I believe your question may be based on what we read in Galatians 1:15-19, “But when it pleased God, who separated me from my mother’s womb, and called me by his grace, To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood: Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus. Then after THREE YEARS I went up to Jerusalem to see Peter, and abode with him fifteen days. But other of the apostles saw I none, save James the Lord’s brother.”

Let’s back up a little in that chapter and read verses 11-12, “But I certify you, brethren, that the gospel which was preached of me is not after man. For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.”  Perhaps from verses 15-19, some might think that Paul was mentored by the Lord for three years, and indeed all he preached and wrote, he received by revelation of Jesus Christ.  He wrote in 1 Corinthians 14:37, “If any man think himself to be a prophet, or spiritual, let him acknowledge that the things that I write unto you are the commandments of the Lord.”  The Lord used Paul to write many letters (epistles).  He also wrote in 2 Timothy 3:16-17, “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.”  This shows us that all the ones the Lord used to write His scriptures were all inspired of Him in writing every single letter and word.

There, however, is no evidence that Paul ever met the Lord in the flesh.  Barnabas commented on Paul’s time in Damascus.  We read in Acts 9:26-27, “And when Saul was come to Jerusalem, he assayed to join himself to the disciples: but they were all afraid of him, and believed not that he was a disciple. But Barnabas took him, and brought him to the apostles, and declared unto them how he had seen the Lord in the way, and that he had spoken to him, and how he had preached boldly at Damascus in the name of Jesus.”  Before a life of ministry, it is so vital that one spend time alone learning God’s Word and how to rightly divide it. (Read 2 Timothy 2:15).  It is this ‘alone’ time with the Lord that will prepare a true believer for a life of service to Himself.  Evidently, Barnabas had witnessed the work of Paul in Damascus and told the apostles so they would be more faithful in receiving him among themselves.

The first instance we have where Paul actually met the Lord is in Acts 9:1-9 (which Barnabas referred to), but we will look at verses 3-5, “And as he journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven: And he fell to the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me? And he said, Who art thou, Lord? And the Lord said, I am Jesus whom thou persecutest: it is hard for thee to kick against the pricks.”  Of course, this is the risen Savior who was now in His glorified body.  We read in 2 Corinthians 5:16, “Wherefore henceforth know we no man after the flesh: yea, though we have known Christ after the flesh, yet now henceforth KNOW WE HIM NO MORE.”  We know the risen Savior, we serve the risen Savior, and we learn from the risen Savior by being faithful students of His Word.  May we all, as believers on the Lord Jesus Christ, give ourselves over to studying God’s Word every day…learning OF Him and learning FROM Him.  (CC)  (667.6)
