The security of salvation for the believer is in the gospel, not in the particular convictions we hold. Paul makes this point repeatedly in his epistles, using this truth as the foundation for the unity of the church. The diversity among believers isn’t a cause for concern, but rather, reflects the great multitude God is saving through Christ.
