I have become all things to all men

1 Corinthians 9:22
to the weak I became as[f] weak, that I might win the weak. I have become all things to all men, that I might by all means save some.

Paul has given himself totally to serving God. There was no prejudice in him nor choosing the way he wanted to serve God. He did not plan to preach to a certain group of people, in fact he would have preferred to preach to his own people, but God had appointed him to preach to the Gentiles. So as God calls us, all we need is to obey, instead of telling God to bless us once we have made all the plans for ministry.
