Philippians 1:12, 14

Now I want you to know, believers, that what has happened to me [this imprisonment that was meant to stop me] has actually served to advance [the spread of] the good news [regarding salvation].

Because of my chains [seeing that I am doing well and that God is accomplishing great things], most of the brothers have renewed confidence in the Lord, and have far more courage to speak the word of God [concerning salvation] without fear [of the consequences, seeing that God can work His good in all circumstances].
