What does the Bible say about preserving the truth of the gospel?

The Bible highlights the necessity of preserving the truth of the gospel, as Paul makes clear in Galatians 2:5, where he states that the truth of the gospel must continue without compromise. Paul stands firmly against any distortion of the gospel, as illustrated by his confrontation with Peter. Such devotion to the gospel's truth shows that it supersedes all personal relationships and pressures. The truth must be safeguarded at all costs to prevent confusion among believers, especially new converts.
