Come home to the One, Holy, Catholic and Apostolic Church.
The Apostle Paul is the minister to the Gentiles, which is all of us, and God and Christ Jesus appointed Paul this minister to the Gentiles to preach the Grace of God and Salvation without works of the Law. Even the Jewish Apostle Peter warned that we all should heed and follow our beloved brother Paul in all the wisdom give unto him:
The Apostle Peter writes - II Peter 3:15: And account that the longsuffering of our Lord is salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you;
The Apostle Paul writes - Romans 2:16: In the day when God shall judge the secrets of men by Jesus Christ according to my gospel.
Peter never wrote to men that we are judged by Jesus Christ according to Peter's gospel - this Gospel was commissioned to Paul by Christ Jesus and God the Father. Heed God's Word and believe the Gospel of Grace which Paul is the minister to us Gentiles.
But what do we find Peter writing:
II Peter 3:15: And account that the longsuffering of our Lord is salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you;
II Peter 3:16: As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction.
God desires that all who have put their faith in Christ KNOW that they have eternal life In Christ. The Bible declares by God's Word that there is NO CONDEMNATION to the believer who has the faith of Christ and believes in Christ Jesus's cross and resurrection [Romans 8:1]. The most important thing to know is that we are saved the very second we have put our trust in Christ. This is what God says, not what any man says: neither are we destined for purgatory - rather, we are 100% certain that we will be in heaven just as Christ Jesus is in heaven with the Father. But our destination is even more secure than that, for the Apostle Paul writes that we ALREADY have all the heavenly blessings in Christ [Eph 1:3].
Ephesians 1:3: Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ:
