1 Corinthians 1:26-31

Now remember what you were, my friends, when God called you. From the human point of view few of you were wise or powerful or of high social standing. God purposely chose what the world considers nonsense in order to shame the wise, and he chose what the world considers weak in order to shame the powerful. He chose what the world looks down on and despises and thinks is nothing, in order to destroy what the world thinks is important. This means that no one can boast in God's presence. But God has brought you into union with Christ Jesus, and God has made Christ to be our wisdom. By him we are put right with God; we become God's holy people and are set free. So then, as the scripture says, “Whoever wants to boast must boast of what the Lord has done.”
