NET
10 But by the grace of God I am what I am, and his grace to me has not been in vain. In fact, I worked harder than all of them—yet not I, but the grace of God with me.
Darby
10 But by God's grace I am what I am; and his grace, which [was] towards me, has not been vain; but I have laboured more abundantly than they all, but not *I*, but the grace of God which [was] with me.
KJV
10 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.
