“For if we are beside ourselves, it is for God; or if we are of sound mind, it is for you” (2 Corinthians 5:13).
The expression “beside ourselves” is a phrase that literally means “out of one’s mind” or “insane.” (1) Paul the Apostle was quite familiar with this allegation for this was a charge that was once leveled against him. That account is recorded in the New Testament book of Acts and involves Paul’s courtroom appearance before a Roman procurator named Porcius Festus and another ruler named Herod Agrippa II…
“Now as he thus made his defense, Festus said with a loud voice, ‘Paul, you are beside yourself! Much learning is driving you mad!’ But he said, ‘I am not mad, most noble Festus, but speak the words of truth and reason. For the king, before whom I also speak freely, knows these things; for I am convinced that none of these things escapes his attention, since this thing was not done in a corner. King Agrippa, do you believe the prophets? I know that you do believe.’
Then Agrippa said to Paul, ‘You almost persuade me to become a Christian.’ And Paul said, ‘I would to God that not only you, but also all who hear me today, might become both almost and altogether such as I am, except for these chains'” (Acts 26:24-29).
Of course, Paul was not the only Christian to stand accused of insanity for even Jesus withstood a similar charge (see Mark 3:21). On the other hand, Paul’s commitment to minister to a group of people who often seemed to have little appreciation for him (like the Corinthians) may have led a casual observer to conclude that he was crazy. The problem was that a person who held that opinion was someone who didn’t have all the facts.
You see, Paul’s commitment to ministry had its origin in God’s calling on his life. In a similar manner, others may question the wisdom of investing in a ministry that no seemingly right-minded person would ever undertake as we seek to fulfill God’s calling. However, a commitment to follow God’s clear direction is always the right choice no matter how foolish it may appear to others.
As one commentary explains…
“Would a sane person willingly face a riotous mob intent on destroying him? (Act_19:30; Act_21:35-40) Who would be crazy enough to walk back into a city in which he had just been stoned and dragged out? (Act_14:19-20) Only a person who was utterly devoted to God would show so little regard for himself. Such a man was Paul” (2)
