Horatius Bonar emphasizes God's divine jealousy for the truth, asserting that His eyes are constantly watching over it to guard and maintain it. He explains that there is only one standard of truth, which is definite, universal, and found in the Bible, and that God holds humanity accountable to this standard. Bonar warns against the laxity of thought in contemporary society, urging individuals to believe in the truth rather than speculate. He calls for a commitment to truthfulness in thought and action, reminding listeners that the day will come when truth will be exalted and error will be condemned. Ultimately, Bonar encourages everyone to align their beliefs with God's unwavering standard of truth.

John Owen emphasizes that the person of Christ is the ultimate source and representation of divine truth, which is essential for understanding God's nature and will. He explains that all truth derives from God, with Christ being the essential image of the Father and the repository of all supernatural truths. Owen argues that without recognizing Christ's central role, spiritual truths lose their light and efficacy, rendering them ineffective in transforming lives. He warns that rejecting Christ leads to a distortion of all other truths, as they are interconnected through Him. Ultimately, true knowledge of divine truth is only possible through a relationship with Christ, who is the life and light of all understanding.
