The Called. Romans 1:6 No longer are we independent. We have been identified as "the called" of Jesus Christ. No longer can we choose what we want to accept or reject. Those subject to "the faith" are "the called" of Jesus Christ. This is the highest possible calling. Some of "the called" came from idol worshipping religious forms to worshipping the Person of Jesus Christ. Some came from the skeptical schools of existentialism to "the faith" and are "the called" of Jesus Christ. Some are called from the doubts of agnosticism and atheism to faith in the Lord Jesus Christ and are numbered among "the called" of Jesus Christ.
Paul’s apostleship was to bring people of all nations to obedience to God based on faith in the Lord Jesus Christ. The words “you also” indicate that Gentile believers were becoming the dominant group in the church in Rome. Paul was the apostle to the Gentiles, so he wanted them to be sure that he had the authority to teach them the word of God even though he had never been there and had not likely seen many of them. His written words had divine authority because the Holy Spirit guided them. Paul wanted the Gentile believers to know they were as much “the people of God” as were the Jews.
The heavenly delineation is given to Him in this context. He is the One from heaven who is now in heaven and calling from the world's nations a people for His name. Those He called belong to Him. He identifies them, and they are to live for Him. This is not some sleight of hand or casual picking and choosing. "The called" belong to Jesus Christ by His sovereign choice. When their calling by the Gospel to hear and believe in the Lord Jesus Christ has brought them to faith in Christ, we look back and see the marvelous grace of God to us in making us be among "the called."
This was no insignificant act on God's part, and I should never consider anything I might do insignificant. It may seem like that in my eyes and other people's eyes, but when God calls us, any service He had in mind for us to accomplish for Him has a noble purpose that can only be valued by Him. "Of His fullness have we received," and grace is given for grace needed to fulfill our God-given calling.
The words “Grace and peace” were typical greetings in that place. “Grace” (charis) was a typical greeting of Greeks when they met. “Peace” (shalom) was the common greeting of Jews in those days and is still part of the language of greetings in some Jewish communities.
