In 1 Cor 1 , Paul addresses some struggles within the Corinthian church, including divisiveness and understanding the wisdom of God. In his introduction, Paul says he is writing to those "who have been called by God to be his own holy people" (v.2), since he is about discuss their need for spiritual unity and Christlike character. He says that just like all believers everywhere, they share the same privilege of being made holy by means of Jesus Christ. Paul then gives thanks to God for them and affirms their spiritual gifts and their standing before God. He encourages them, explaining that God will preserve them and "keep them strong right up to the end", and will "keep them free from all blame" on the great day when Jesus returns (v 8). Paul reminds them again that God is the one who called them into fellowship with His Son Jesus, and He is faithful and will surely preserve them, "for He always does just what He says" (v.9). Once under grace, always under grace. As Paul addresses the issue of unity, he mentions Christ over and over (10 times in v. 1-10) to emphasize that believers are all in allegiance to the same Christ Jesus. He says , "dear brothers", emphasizing the family of God in his appeal to them to stop arguing and to be "united in thought and purpose". Next, Paul addresses their misunderstandings about human wisdom and God's wisdom. He explains that nobody can find God through human wisdom alone, since the message of the cross sounds foolish to those who are not called by God to salvation. "Christ is the mighty power of God and the wonderful wisdom of God" (v.24). Paul reminds again that "God alone made it possible for you to be in Christ Jesus" (v.30) and therefore "Let him who boasts, boast in the Lord"(v31).
