<p>2:12- see on 1 Cor. 16:9.</p><p><em>Now when I came to Troas for the sake of the gospel of Christ and when a door was opened to me in the Lord- </em>As noted on 1:23, Paul changed his intention to visit Corinth on his way to Macedonia. He travelled via Troas- and that decision was blessed because a door was opened to him there in the Gospel's work. Frequently Paul uses the word &quot;Gospel&quot; as meaning 'the preaching of the Gospel'; the Gospel is in itself something which <em>must</em> be preached if we really have it (Rom. 1:1,9; 16:25; Phil. 1:5 (NIV),12; 2:22; 4:15; 1 Thess. 1:5; 3:2; 2 Thess. 2:14; 2 Tim. 1:8; 2:8). The fact we have been given the Gospel is in itself an imperative to preach it. &ldquo;When I came to Troas for the Gospel of Christ&rdquo; (2 Cor. 2:12 RV) has the ellipsis supplied in the AV: &ldquo;to preach Christ&rsquo;s Gospel&rdquo; although there is no Greek word in the original matching &lsquo;preach&rsquo; .</p>
