2 Corinthians 2:12-14

Now when I arrived at Troas to preach the good news of Christ, even though a door [of opportunity] opened for me in the Lord, my spirit could not rest because I did not find my brother Titus there; so saying goodbye to them, I left for Macedonia. But thanks be to God, who always leads us in triumph in Christ, and through us spreads and makes evident everywhere the sweet fragrance of the knowledge of Him.
