II Corinthians 2:11-15

lest Satan should take advantage of us; for we are not ignorant of his devices. Furthermore, when I came to Troas to preach Christ’s gospel, and a door was opened to me by the Lord, I had no rest in my spirit, because I did not find Titus my brother; but taking my leave of them, I departed for Macedonia. Now thanks be to God who always leads us in triumph in Christ, and through us diffuses the fragrance of His knowledge in every place. For we are to God the fragrance of Christ among those who are being saved and among those who are perishing.
