650 B

because of the grace that was given to me

Here "grace" refers to God choosing Paul to be an apostle and leader of the church. Alternate translation: "because God freely chose me to be an apostle."

that everyone who is among you should not think more highly of oneself than he ought to think

"that no one should think they are better than other people"

but to think so as to think wisely

This could be translated as a new sentence:"But you should be wise in how you think about yourselves"

just as God has given out to each one a measure of faith

"since God has given you the amount of faith you need to think correctly"
