VERSE 20. Now the things which I write unto you, behold, before God, I lie not. Was it necessary for Paul to go under oath? Yes. Paul is reporting personal history. How else would the churches believe him? The false apostles might say, "Who knows whether Paul is telling the truth?" Paul, the elect vessel of God, was held in so little esteem by his own Galatians to whom he had preached Christ that it was necessary for him to swear an oath that he spoke the truth. If this happened to Paul, what business have we to complain when people doubt our words, or hold us in little regard, we who cannot begin to compare ourselves with the Apostle?
