“But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me.”
King James Version (KJV)
15:10 I laboured more than they all - That is, more than any of them, from a deep sense of the peculiar love God had shown me. Yet, to speak more properly, it is not I, but the grace of God that is with me - This it is which at first qualified me for the work, and still excites me to zeal and diligence in it.
1Co 15:10 But by the grace of God I am what I am. Not by his own merit, which he considered so small, but by God's grace he had been enabled to do a more abundant work than any other apostle.
