On plain preaching

Not with enticing words of man's wisdom, but in demonstration of the Spirit, and of Power [1 Corinthians 2:4]. Use sound words that cannot be condemned. Rhetorical flashes are like painted glass in a window, that makes a great show, but darkens the light; ... The Prophets and Apostles generally spoke in the vulgar and common languages which the ordinary people understood: They did not only speak to the understanding of a King upon the throne, but to the understanding of the meanest subject.

Perseverance

God superintends the activity of his gospel-bearer who perseveres in the most extreme circumstances. Therefore, we should persevere in ministry and God will bring his purposes to fruition. God will triumph, but not apart from human persistence, a capacity which he gives us.
