Colossians 4:3-4
At the same time, pray also for us, that God may open to us a door for the word, to declare the mystery of Christ, on account of which I am in prison— that I may make it clear, which is how I ought to speak.

The design of gospel tracts is to awaken the minds of men, and to excite in them a sense of their danger and their need of a Savior.
Jonathan Edwards
