Passage
But by the grace of God I am what I am: and his grace which was bestowed upon me was not found vain; but I labored more abundantly than they all: yet not I, but the grace of God which was with me.
But by the grace of God I am what I am: and his grace which was bestowed upon me was not found vain; but I labored more abundantly than they all: yet not I, but the grace of God which was with me.
1 Corinthians 15:8 and last of all, as to the [child] untimely born, he appeared to me also.

1 Corinthians 15:10 But by the grace of God I am what I am: and his grace which was bestowed upon me was not found vain; but I labored more abundantly than they all: yet not I, but the grace of God which was with me.
1 Corinthians 15:11 Whether then [it be] I or they, so we preach, and so ye believed.
1 Corinthians 15:12 Now if Christ is preached that he hath been raised from the dead, how say some among you that there is no resurrection of the dead?
The verse centers on "grace", "bestowed", "upon", "found", "vain", "labored", and "abundantly". It is saying that the verse draws attention to "grace" and "bestowed", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "For I am the least of the..." into verse 11's "Whether then it be I or they...", so "grace" and "bestowed" belong inside that flow. In 1 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "grace" and "bestowed" with trust shaped by these words, not by a vague optimism outside the passage.
