Bruce meticulously examines Paul's second visit to Jerusalem, fourteen years after his conversion or previous visit, maintaining its prestige in validating Paul's gospel. Bruce analyzes whether the fourteen years refer to Paul's conversion or earlier visit, referencing scholars G. Ogg and R. Jewett. This adventure with Barnabas and Titus indicated Paul’s first substantial interaction with Jerusalem church leaders since Galatians 1:18. Barnabas played a decisive role in early Christianity, while Titus, a Gentile Christian, accompanied Paul to demonstrate that grace suffices without circumcision, aligning with Luther's interpretation. The absence of Titus in Acts is discussed, with speculations on his connections to Luke or involvement in the Jerusalem relief fund. Further, Bruce dives into Paul's visit to Jerusalem mentioned in Galatians 2:2, debating its connection to Agabus's prophecy or the Spirit's command in Acts 13:1-2. Paul’s visit, urged by a revelation, aimed to affirm his mission to the Gentiles. His private consultation with esteemed leaders—James, Cephas (Peter), and John—was strategic, ensuring a sympathetic hearing and avoiding conflict. Bruce points out Paul’s concern about maintaining church unity for the Gentile mission's success. The commentary discusses Titus's non-circumcision, affirming the law-free gospel for Gentiles, and the "false brothers" attempting to impose legalistic practices. Besides, Paul's claim that Jerusalem leaders added nothing to his gospel reiterates his autonomous authority from Christ. Bruce discusses "pillars" for James, Peter, and John, repeating their constitutional church roles. The Jerusalem conference formalized mission fields: Paul and Barnabas to Gentiles, James, Peter, and John to Jews, symbolized by exchanging fellowship. Paul’s instruction to "remember the poor" underlines his social responsibility assurance, exceptionally through famine relief efforts. Lastly, Bruce interprets Paul’s declaration in Galatians 2:16 that justification is through faith in Christ, not by the law's works, unifying Jewish and Gentile believers under a new covenant. Paul’s contention of dying to the law to live for God symbolizes a shift from legal bondage to new life in Christ, underscoring the sufficiency of Christ's sacrifice. Bruce integrates scholarly perspectives, providing a thorough examination of early Christianity, where divine revelation, apostolic authority, and mission strategy shaped the developing Christian movement.
