Paul vs. Luke

The apostle Paul said in Galatians 1:20, "Now the things which I write unto you, behold, before God, I lie not." So, who said Paul was lying about the things he said in Galatians 1? The writer of the Acts (supposedly Luke) did.

Luke said that Paul was struck blind and led about by hand and was taught the things he must do and was baptized by the disciples at Damascus (Acts 9: 18-19).

Paul said nothing about being struck blind but that he received a revelation from God and Jesus Christ and that he conferred not with flesh and blood but went into Arabia and returned to Damascus (Gal. 1:11-17).

Luke said that Paul went to Jerusalem and tried to join the disciples but they were afraid of him and that Barnabus brought Paul before the apostles. Then Paul was with them (the disciples) going in and coming out at Jerusalem  (Acts 9:26-28).

Paul said that he went to Jerusalem after 3 years of preaching his gospel and went to see Peter and stayed with him for 15 days and didn't see any of the other apostles except James. (Gal. 1:18-19).

Luke said that Paul was summoned to Jerusalem about the circumcision dispute and went preaching his gospel to all and then went into private conference with the apostles (Acts 15: 1-5).

Paul said that he went up to Jerusalem by revelation and spoke to the apostles privately (Gal. 2:1-2).

Luke says that the apostles added three things to Paul's gentile converts and instructed that they could learn the rest of the law of Moses by attending the synagogues in every city (Acts 15:19-21).

Paul said that "they added nothing to me" (Gal. 2: 6).

Luke said that Paul was in subjection to the other apostles (Acts 15) Paul said he wasn't (Gal. 2). But, remember that Paul said, "before God, I lie not". No doubt, somebody was lying...
