Take every opportunity which your nearness provides to be speaking seriously to each other about the matters of God, and your salvation. Discussing those things of this world no more than required. And then talk together of the state and duty of your souls towards God, and of your hopes of heaven, as those that take these for their greatest business. And don't speak lightly, or unreverently, or in a rude and disputing manner; but with gravity and sobriety, as those that are discussing the most important things in the whole world.
