<p>15:20 <i>Yes, making it my aim to preach the gospel, not where Christ was already named, that I might not build upon another man's foundation</i>- Paul appears to have had a policy of breaking fresh ground for the Gospel and not getting involved where someone else had preached. It was his aim to spread the Gospel. He implies therefore that there were others preaching the Gospel apart from him. The metaphor of building is in context of Paul's teaching that they should be building one another up (a closely related word is used in 14:19; 15:2). Always Paul consciously sets himself up as their example. He has reasoned that just as the Holy Spirit is at work in the hearts of the Gentile converts in Rome to sanctify them, so the same Spirit has been at work with him in his missionary work. He sees a huge unity of the Spirit throughout. And likewise he speaks of how they in Rome can build each other up, including the Jewish brethren building up the Gentiles, just as he is at work empire-wide building up the Gentile converts. When a person is baptized, they call upon themselves the name of the Lord Jesus. &quot;Where Christ was already named&quot; may therefore refer to areas where there had already been converts made.</p><p>Paul read the OT prophecies of how &ldquo;to whom he was not spoken of, they shall see&rdquo;; and he didn&rsquo;t just see them as descriptions of what would ultimately happen. He realised that the fulfilment of this prophecy depended <i>to some extent</i> on our human freewill; and therefore he <i>strove </i>(against so many odds) to preach Christ where He had not yet been named (Rom. 15:19,20). And he asks the Romans to <i>strive together </i>with him in prayer (15:30)- i.e. to join him in the struggle to witness world-wide, in that they would pray for his success. It was God&rsquo;s prophesied will that the Gospel would go world-wide; but it required the freewill strivings of Paul to enable it, and the strivings with God in prayer by the brethren.</p>
