I found this article in Bible Treasury, and thought it worth sharing: "Salvation and Sealing".

The moment I see myself all sin, I may see all this grace shown me, just as much accepted now as when before Him in the glory. This I have not yet got; I am only waiting for the glory, but I am now accepted in the beloved. One must be either in sin before God, or in Christ accepted. There is no middle state. If looking at myself, I must be condemned; but if I rest on His sovereign goodness, the riches of His grace are mine in the gift of His Son, not dying only for sinners, but risen and in heaven, and myself accepted in Him. In Him I have redemption through His blood. In this there is nothing vague.

I have no idea who wrote it, but it's really quite good.
