The Passover and Feast of Unleavened Bread serves as a picture of Christ's sacrifice for us. Paul points this out to the Corinthians and tells them that like leaven which was to be put out of their homes at Passover, so the leaven of sin must be put out from among them.
God's command to His people is that the wicked who claim to be Christians are to be put out of the church. The Passover is a picture of how the church is to be pure - clean out the leaven because Christ our Passover has been sacrificed.
Paul admonishes the Corinthians for their arrogance in failing to grieve over gross sin in their midst and to put such a professing Christian out of the church.
Paul admonishes the Corinthians for their arrogance. He shows them his experience in following Christ and rebukes them for puffing themselves up in pride. The church of today needs this rebuke.
The church has been entrusted with a treasure - the gospel - which must be guarded carefully and faithfully. Otherwise we will be found unfaithful when Christ comes again. We are stewards of this pearl of great price and we must never alter it no matter how much pressure people with itching ears crave another gospel.
When Paul tells us to be renewed in the spirit of our mind, he means that the very essence and depth of the sinner's being is corrupted so that the mind is darkened, blinded, and broken. It cannot process God's Revelation to us and twists His truth into a lie.
The world's wisdom is foolishness to God. If we are going to be wise in God's real wisdom, we must be willing to be regarded as fools by the world.
Faith is a gift from God given when He makes us new creations. Faith embraces the wisdom of God even though the world calls it foolishness. Without faith, it is impossible to please God. Man the sinner cannot and will not believe God's Word.
The wisdom of God, the truth of Christ and His Word and gospel, is only seen and heard by the work of the Holy Spirit in us. A real Christian is a person who had heard Christ, who has learned Christ, who has been taught Christ - all by the life-working work of the Holy Spirit. Apart from this spiritual work in us by the Spirit, we would never HEAR Christ.
We must be careful to build Christ's church upon the one true foundation - which is Jesus Christ. And we must be careful to add to that foundation by the foolishness of the message preached - Jesus Christ and Him crucified. We must never mingle the wisdom or methods of the world with the gospel.
