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).
