God’s way of salvation through the redeeming work of Christ alone has often been misunderstood and even caricatured. It may be portrayed as unworthy of God (how can God require nothing of sinners?) or as promoting immorality (is there no place for obeying God’s law?). Such objections arose even in New Testament times and were current at many times in church history. We now consider Galatians 2:17-21 Christ lives in me.
1. A mistaken path
Paul is still setting out the truth of the gospel in the context of the controversy in Antioch, with the Judaizers seeking to add obedience to the Mosaic law as necessary for salvation. Paul’s key statement is in v16 ‘a man is not justified by observing the law, but by faith in Jesus Christ’. In v17 Paul deals with the objection of the Judaizers to his teaching. They argued that Paul denied the need for law-keeping to be saved and relied only on faith, yet sin was still evident in his life – ‘does that mean that Christ promotes sin?’ The Judaizers blame his doctrine of justification by faith for the sin that remains in his life. Is Christ a sin-promoter? Paul is emphatic – ‘Absolutely not!’ (v17). Paul is not being inconsistent, unlike Peter. Justification by faith is the gospel and must be maintained and defended.
2. A saving union
Paul develops his argument that faith in Christ cannot be encouraging sin. Paul knew from his own experience that efforts to keep the law could not save – see Romans 7:7. The law exposed sinfulness and even promoted it. This, however, set him on the right path. He lays out the heart of the gospel in v20 ‘I have been crucified with Christ ‘ -this is how a sinner may live. Paul speaks of a spiritual union between Christ and his people. Thus Romans 6:5 ‘we have been united with him in his death, we will certainly also be united with him in his resurrection’. Our sin was laid on Christ and his righteousness is counted as ours. Hence we are justified ‘by faith in Christ’ (v16). We receive all the benefits flowing from Christ’s death and resurrection. Even more wonderful – ‘but Christ lives in me’ (v20). This is the glorious privilege enjoyed by all who are in union with Christ. Spiritually we are indwelt by the Saviour through the ministry of the Holy Spirit. Note Colossians 1:27 ‘Christ in you, the hope of glory’.
3. A transformed life
Union with Christ changes everything. The believer is dead to sin – it will never again be his master, yet he still lives – ‘The life I now live in the body I live by faith in the Son of God’ (v20). The entire life of the believer depends on and has its focus on Christ. It is to be lived ‘by faith’ – the very opposite of dependence on law-keeping. The gospel keeps bringing us back to the cross. There we see ‘the Son of God who loved me and gave himself for me’. The definitive historical event of the cross is central to God’s provision. The contrast between the mistaken path and the gospel path is absolute. ‘I do not set aside the grace of God’ (v21). If works contribute to salvation, ‘Christ died for nothing’. No place can be given to works in the reception of salvation, or the gospel is forfeited.
