God chose mostly despised, not important, people to belong to Christ; so you should boast only about him.

1 Corinthians 1:26-31

26 My fellow believers, remember what kind of people you were when God chose you. Not many of you whom he chose are people whom unbelievers considered to be wise. Very few of you were considered to be important. Very few of you came from families with a high social standing. 27 Instead, it was usually those whom unbelievers considered to be foolish whom God chose. He did that in order to shame/discredit those whom unbelievers consider [IRO] wise. It was usually those whom unbelievers considered [IRO] unimportant whom God chose, in order to shame/discredit those whom unbelievers consider important. 28 It was usually those who are despised and considered {whom unbelievers despise and consider} worthless whom God chose, in order to make completely ineffective what unbelievers consider to be important. 29 He did that in order that no one could boast to God about being wise or important. 30 It is because of what God has done that you ◄have a close relationship with/belong to► Christ Jesus. God put into effect his wise plan to save us by what Christ did for us. As a result of what Christ did, God erases the record of our sins, sets us apart for himself, and frees us from our being guilty for our sins. 31 So, it is the Lord whom we should boast about, not about one spiritual leader being better than another. We should do as ◄a prophet/Jeremiah► wrote in the Scriptures that we should do:

Those who boast should boast only about what the Lord has done.
