Romans 15:15 But on some points I have written to you very boldly by way of reminder, because of the grace given me by God 16 to be a minister of Christ Jesus to the Gentiles in the priestly service of the gospel of God, so that the offering of the Gentiles may be acceptable, sanctified by the Holy Spirit. 17 In Christ Jesus, then, I have reason to be proud of my work for God. 18 For I will not venture to speak of anything except what Christ has accomplished through me to bring the Gentiles to obedience- by word and deed, 19 by the power of signs and wonders, by the power of the Spirit of God- so that from Jerusalem and all the way around to Illyricum I have fulfilled the ministry of the gospel of Christ; 20 and thus I make it my ambition to preach the gospel, not where Christ has already been named, lest I build on someone else's foundation, 21 but as it is written, "Those who have never been told of him will see, and those who have never heard will understand."
Romans 15:15-16 display God’s will for us through the life of Paul. We are to use the grace given us by God to serve people so that their lives are acceptable to God by the power of Holy Spirit. We need to serve the people God has sent us to so that we can say like Paul, “In Christ Jesus I have reason to be proud of my work for God.” “Am I using the grace given me by God to serve people so they are acceptable to God?” is a question we need to ask of ourselves often.
In Romans 15:18a the Apostle Paul tells us why he could be proud of his work for God. Christ was working through Paul to accomplish the work of God. In Galatians 2:20 Paul states, “I have been crucified with Christ and I no longer live but Christ lives in me. The life I live in the body I live by faith in the Son of God, who loved me and gave Himself for me.” Paul did not hinder Christ from working through him to accomplish God’s work. He attempted to do God’s work expecting Christ to fulfill his attempt with power. Paul states this in another way in Colossians 1:28-29, “Him we proclaim, warning everyone and teaching everyone with wisdom, that we may present everyone mature in Christ. For this I work struggling with all His energy that He powerfully works within me.” Paul was fully engaged in God’s work using to the fullest extent the power of Christ who lived in him and through him. We can do the same thing as we live by faith in the Son of God.
Paul knew what work he was to do by means of the word of God as taught him by the Holy Spirit (John 14:6) and by the gifts given him by the Holy Spirit (1 Corinthians 12:11). He knew from Jesus’ great commission recorded now in Matthew 28:19-20, that he was to teach the people to obey everything Jesus had commanded the apostles. He knew from his gifts (apostle, teacher) that he was to preach the word. He knew from the word of God in Isaiah 52:7, 15 that he was to take the gospel to those who had never been told. Are you spending time in the word and prayer to get your assignment from God? Are you letting your gifts of grace direct your work for God? Every believer has God assigned work to do and is responsible for getting it done using the resources given him by God. The completed work brings God’s benefits to many people and brings great fulfillment and joy to the worker.
