This special revelation of God is a revelation of redemption. It reveals the plan of God for the redemption of sinners and of the world, and the way in which this plan is realized. It is instrumental in renewing man; it illumines his mind and inclines his will to that which is good; it fills him with holy affections, and prepares him for his heavenly home. Not only does it bring us a message of redemption; it also acquaints us with redemptive facts. It not only enriches us with knowledge, but also transforms lives by changing sinners into saints. This revelation is clearly progressive. The great truths of redemption appear but dimly at first, but gradually increase in clearness, and finally stand out in the New Testament in all their fullness and beauty.
