To the praise of the glory of His grace, wherein He hath made us accepted in the Beloved. – 1 Ephesians 1:6

I believe that many of you have had an experience similar to mine, and that there have been times when you have been living specially near to God, and walking in the light of his countenance, when, on a sudden, the sin that dwelleth in you has seemed to attack you just when you least expected it. I know that my fiercest temptations often come to me immediately after my highest enjoyment of communion with God… Well, I believe that, at such times, Christians try to nestle closer than ever under the wings of God, and they feel humbler, and they go to the precious blood of Jesus with a more intense desire to prove again its cleansing power; and they cry to the Strong for strength, and they feel, more than ever they did before, their need of the Holy Spirit’s sanctifying power. Ralph Erskine said that he was more afraid of a sleeping devil than of a roaring devil, and there was good reason for his fear, for when the devil was roaring, the saints would be more on the watch than when he was quiet. The worst temptation in the world is not to be tempted at all; but when there is a strong temptation, and your soul is fully aware of it, you are on your guard against it. The wave of temptation may even wash you higher up upon the Rock of ages, so that you cling to it with a firmer grip than you have ever done before, and so again where sin abounds, grace will much more abound.

O beloved, when your sin abounds, then is the time to recollect that grace much more abounds. Sinner as you are, you are forgiven, you are “accepted in the Beloved,” you are saved, you are a child of God, you shall be in heaven ere long, to praise for ever the grace that shall be crowned with glory. ~ C.H. Spurgeon
