The wise man must not boast of his wisdom, nor the strong man of his strength, nor the rich man of his riches. What then is the right kind of boasting? What is the source of man’s greatness? Scripture says: The man who boasts must boast of this, that he knows and understands that I am the Lord. Here is man’s greatness, here is man’s glory and majesty: to know in truth what is great, to hold fast to it, and to seek glory from the Lord of glory. The Apostle tells us: The man who boasts must boast of the Lord. He has just said: Christ was appointed by God to be our wisdom, our righteousness, our sanctification, our redemption, so that, as it is written, a man who boasts must boast of the Lord. Boasting of God is perfect and complete when we take no pride in our own righteousness but acknowledge that we are utterly lacking in true righteousness and have been made righteous only by faith in Christ.
