“As a result, no one can ever boast in the presence of God. God has united you with Christ Jesus. For our benefit God made him to be wisdom itself. Christ made us right with God; he made us pure and holy, and he freed us from sin.” 1 Corinthians 1:29-30
God shows His wisdom by means of righteousness, sanctification and redemption in Jesus Christ. These are things that Christ did for us. Jesus Christ is our wisdom. It is only in following Him that we can have life and life more abundant. It is only by listening to Him that we can know the truth. Jesus Christ is our righteousness. In the writings of Paul righteousness always means a right relationship with God. Of our own efforts we can never achieve that. It is ours only by realizing through Jesus Christ that it comes not from what we can do for God, but from what he has done for us. Jesus Christ is our sanctification. We belong to God and we are set apart from the world to serve God. Jesus Christ is our redemption. Jesus Christ is the only one that can free us from our sins of the past and help us in the present. He can give us peace about the future.
The Corinthian church was glorying in men and we must glory in God only, because He is the only true wisdom in the world.
“But those who wish to boast should boast in this alone: that they truly know me and understand that I am the Lord who demonstrates unfailing love and who brings justice and righteousness to the earth, and that I delight in these things. I, the Lord, have spoken!” (Jeremiah 9:24)
