Read 1 Corinthians 1.
Was there ever a more mixed-up group of Christians than the believers in Corinth?
Although they had been blessed by the ministries of several faithful men (v. 12), they could not receive and each man’s teaching. Instead of seeing each man’s ministry as one part of God’s complete instruction to them, they took sides. They claimed to follow one of these men as if they were in opposition to each other instead of co-workers for Christ.
In addition to their divisions, they were confused about what God’s grace meant and about several points of Christian doctrine. We’ll read about all of this in the coming days, but just know or remember that the church in Corinth had a lot of problems.
Yet, Paul began his letter to them by writing, “To the church of God in Corinth, to those sanctified in Christ Jesus and called to be his holy people, together with all those everywhere who call on the name of our Lord Jesus Christ—their Lord and ours: Grace and peace to you from God our Father and the Lord Jesus Christ” (vv. 2-3).
That greeting gives me great hope. It reminds me that we don’t belong to Christ because we volunteered and worked hard morally to become worthy of being his people.
Instead we are “sanctified in Christ Jesus.” Sanctified means “set apart.” In this context, it refers to our membership in God’s family by faith. It is our association with Christ—being “in Christ Jesus”—that caused us to be set apart to belong to him. It is through the gospel Jesus preached that they and we were “called to be his holy people” (v. 2).
Despite our many differences, we are one in Christ “with all those everywhere who call on the name of our Lord Jesus Christ—their Lord and ours” (v. 2). Despite differences in where we live on earth, or when we live on earth, or age, or language, or anything else, if we’re in Christ, we are one. We all call on the same Lord and that same Lord is working on us, causing us to grow and become like him.
