A common misinterpretation arises from superficially reading 'I lie not' as Paul admitting deceit, when he is actually affirming his truthfulness under God's scrutiny; others might misuse the passage to justify casual oaths or swearing in personal disputes, ignoring its context as Paul's intense doxological appeal during a passionate vindication of his hardships for Christ, not a general endorsement of human vows which Jesus cautions against elsewhere.
II Corinthians 11:31
King James Version (1769)
31 The God and Father of our Lord Jesus Christ, which is blessed for evermore, knoweth that I lie not.
In this verse, Paul solemnly invokes God the Father of Jesus Christ, who is eternally blessed, as the ultimate witness to his truthfulness amid his defense of his apostolic ministry and sufferings. It highlights Paul's unwavering integrity, his deep reverence for God, and his commitment to honesty in proclaiming the gospel, emphasizing that divine knowledge validates his claims against detractors who questioned his authenticity.
