For if I preach (ean gar euaggelizwmai). Third class condition, supposable case. Same construction in verse Luke 16 (ean mh). For necessity is laid upon me (anagkh gar moi epikeitai). Old verb, lies upon me (dative case moi). Jesus had called him ( Acts 9:6Acts 9:15 ; Galatians 1:15 ; Romans 1:14 ). He could do no other and deserves no credit for doing it. Woe is me (ouai gar moi). Explaining the anagkh (necessity). Paul had to heed the call of Christ that he had heard. He had a real call to the ministry. Would that this were the case with every modern preacher.
