If you have anything to boast about, you want to boast it. It’s human nature. Wanting to be acknowledged by someone is the most basic need for human.
…circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; in regard to the law, a Pharisee; as for zeal, persecuting the church; as for legalistic righteousness, faultless. But whatever was to my profit I now consider loss for the sake of Christ. What is more, I consider everything a loss compared to the surpassing greatness of knowing Christ Jesus my Lord, for whose sake I have lost all things. I consider them rubbish, that I may gain Christ and be found in him…Php 3:5-9
The Apostle Paul was born in a good family with a high education; he had a lot of things to boast about. However, the reason he did not impose these things was because he wanted to be acknowledged not by man but by God. As he wanted to be acknowledged by God, except the knowledge of knowing Christ, he considered all of them as rubbish. A life acknowledged by God! If this grants us the blessing of heaven, where can there be a life more blessed than this in the world?
