In my devotional reading this morning I read from Spurgeon's "Morning and Evening," the following words which I think may be as helpful and encouraging to you as they were to me.
It will always give a Christian the greatest calm, quiet, ease, and peace, to think of the perfect righteousness of Christ. How often are the saints of God downcast and sad! I do not think they ought to be. I do not think they would if they could always see their perfection in Christ. There are some who are always talking about corruption, and the depravity of the heart, and the innate evil of the soul. This is quite true, but why not go a little further, and remember that we are “perfect in Christ Jesus.” It is no wonder that those who are dwelling upon their own corruption should wear such downcast looks; but surely if we call to mind that “Christ is made unto us righteousness,” we shall be of good cheer . . . If saved by imputed righteousness, we shall greatly value imparted righteousness.
