{For if I preach} (ean gar euaggeliz(936d)ai). Third class
condition, supposable case. Same construction in verse  16  (ean
m(885c)). {For necessity is laid upon me} (anagk(8820)gar moi
epikeitai). Old verb, lies upon me (dative case moi). Jesus
had called him ( Ac 9:6,15  Ga 1:15f.  Ro 1:14 ). He could do no
other and deserves no credit for doing it. {Woe is me} (ouai gar
moi). Explaining the anagk(885c) (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.
