5 so we, being many, are one body in Christ, and individually members of one another. 6 Having then gifts differing according to the grace that is given to us, let us use them: if prophecy, let us prophesy in proportion to our faith; 7 or ministry, let us use it in our ministering; he who teaches, in teaching; 8 he who exhorts, in exhortation; he who gives, with liberality; he who leads, with diligence; he who shows mercy, with cheerfulness. (Romans 12:5–8, NKJV)
Christians are one body in Christ and members of one another. We are interconnected, joined together in Christ by our common faith and common salvation (Tit. 1:4; Jude 3). (The local church is described this way in 1 Corinthians 12:12-27.) God has blessed us with different gifts, and He calls on us to use them for the benefit of His church. To achieve this requires us to serve each other with humility. Remembering the church belongs to Christ (not us) helps us focus on helping one another instead of demanding that others do our bidding (Phil. 2:1-8). The Son of Man came to serve, not to be served (Matt. 20:28). Like Jesus, use today to focus on serving someone instead of expecting someone to serve you. Doing so will strengthen you and the body of Christ.
4 For as we have many members in one body, but all the members do not have the same function, 5 so we, being many, are one body in Christ, and individually members of one another. (Romans 12:4–5, NKJV)
The church is depicted as a body – its members having different functions, but all aimed toward the singular, united purpose of serving the will of its head, who is Christ. This picture of the church as a body draws our attention to the unity to which we are called as Christians. Division is roundly condemned in the Scriptures as a work of the flesh (Gal. 5:20). Christians are united in our faith, in our common salvation, and in our mutual care for one another. To the extent that Christians refuse to consider ourselves “members of one another,” they contribute to discord in the body of Christ. The church suffers when fellow Christians will not work and worship together in mutual faith, mutual love and mutual reverence for the Lord. Each Christian has an important place in the body of Christ, which includes “endeavoring to keep the unity of the Spirit in the bond of peace” (Eph. 4:3). Each member of the body of Christ is more effective and faithful as we all remember we are “individually members of one another.”
For by one Spirit we were all baptized into one body—whether Jews or Greeks, whether slaves or free—and have all been made to drink into one Spirit. (1 Corinthians 12:13, NKJV)
There is much disagreement and misunderstanding about the work of the Holy Spirit in salvation. This verse will remove some of that misunderstanding – if we will allow it. The Holy Spirit guided the apostles into “all truth” (the gospel), which they preached to the world (Jno. 16:13; Mk. 16:15). This Spirit-given truth calls upon every sinner to believe, repent and be baptized to be saved (Mk. 16:16; Acts 2:38, 41). Thus, by the direction of the Holy Spirit, all Christians have been baptized into “one body” (the church, Acts 2:41, 47). Based upon this truth, Paul makes a plea for all the members of the church to work together in unity. He notes that one Spirit has directed our baptism in water (by the gospel He revealed), and by doing so, every Christian is a member of the body (church) of Christ. We have all drunk of the spiritual blessings given us by “one Spirit.” The Holy Spirit gives a wonderful gift to all who have been saved – spiritual refreshing and “an inheritance among all those who are sanctified by faith” (Acts 2:38; 3:19; 26:18). Because there is “one body” (the church) and “one baptism” (water), Christians must keep the unity of the Spirit, and not be divided (Eph. 4:3-5).
