1Co 15:1-9 NLT "Let me now remind you, dear brothers and sisters, of the Good News I preached to you before. You welcomed it then, and you still stand firm in it. (2) It is this Good News that saves you if you continue to believe the message I told you—unless, of course, you believed something that was never true in the first place. (3) I passed on to you what was most important and what had also been passed on to me. Christ died for our sins, just as the Scriptures said. (4) He was buried, and He was raised from the dead on the third day, just as the Scriptures said. (5) He was seen by Peter and then by the Twelve. (6) After that, He was seen by more than 500 of His followers at one time, most of whom are still alive, though some have died. (7) Then He was seen by James and later by all the apostles. (8) Last of all, as though I had been born at the wrong time, I also saw Him. (9) For I am the least of all the apostles. In fact, I'm not even worthy to be called an apostle after the way I persecuted God's church."
Here is a passage of scripture that puts Paul's understanding of the gospel most succinctly: 2Co 5:16-21 NLT "So we have stopped evaluating others from a human point of view. At one time we thought of Christ merely from a human point of view. How differently we know Him now! (17) This means that anyone who belongs to Christ has become a new person. The old life is gone; a new life has begun! (18) And all of this is a gift from God, who brought us back to Himself through Christ. And God has given us this task of reconciling people to Him. (19) For God was in Christ, reconciling the world to Himself, no longer counting people's sins against them. And He gave us this wonderful message of reconciliation. (20) So we are Christ's ambassadors; God is making His appeal through us. We speak for Christ when we plead, "Come back to God!" (21) For God made Christ, who never sinned, to be the offering for our sin, so that we could be made right with God through Christ."
The gospel according to Paul is this: Humanity has been reconciled to God through Christ. Further, God has given everyone who knows and believes this message the ministry of reconciliation. Even further, God was in Christ reconciling the world to himself not counting sin. Even further, he made Jesus, (the one who did not know the concept of sin) to be MADE SIN so that the rest of us could be made the righteousness of God in Him.
This is the ULTIMATE REVELATION! This is the explanation of the MYSTERY! Why is it that all of evangelical Christianity is so wrapped up in the discussion of sin? Why is there so much focus on sin? Why is there so much discussion of Old Covenant Law? Why is there so much hate, fear and bigotry? The answer is obviously simple; evangelical church doctrine is a complete ERROR!
