Speaking about his own spiritual path, Paul does not stress by chance that, while at one time he was a zealous adherent of Judaism, he later became a witness of Christ, who sent him to preach the gospel to the Gentiles (vv. 13-17). Apparently, in this way the apostle was answering possible reproaches that he himself had sharply changed his views on foundational questions of spiritual and religious life. If that is so, why should the Christians of Galatia not do the same, especially since the changes in their worldview were far less radical than those Paul had experienced?
But the apostle immediately notes a fundamentally important point concerning his spiritual path: the absolute sincerity of his search. If at first he was a zealous supporter of Judaism, it was not because he wanted to be "like everyone else," but because he was sincerely convinced that the way he lived and believed was right before God.
It was precisely this sincerity that helped him meet Christ and acquire the Kingdom. But one meeting on the Damascus road was not enough. Now he had to change his life decisively in order to become a witness of Christ. Here too Paul remained true to himself. He did not begin looking for anyone to confirm the truth of his revelation; he simply went to do the work God had entrusted to him (vv. 15-19).
Such sincerity is a pledge both of spiritual sobriety and of freedom from spiritual error. A spiritually sincere person will never look for detours in spiritual life in order to avoid problems, find an easier way to live in the Kingdom, or seek compromises where they are inadmissible. The preachers who distort the gospel, of whom the apostle speaks, were apparently insisting on the strict obligation for all Christians to observe Jewish religious prescriptions. This was caused most of all, no doubt, by the desire to avoid conflict with the Synagogue, which otherwise became inevitable. Clearly, such "spiritual searches" had nothing to do either with spirituality or with a genuine search. They could only distance a person from the Kingdom, as Paul does not grow tired of reminding them.
