Chalmers said that glimpses into the dark room of the heart alone give no good prospect. Instead, he said we should 

McCheyne had written that down in a class and underlined the last sentence. So it is not surprising to hear him give his own counsel in similar terms: "Learn much of the Lord Jesus. For every look at yourself take ten looks at Christ. He is altogether lovely . . . . Live much in the smiles of God. Bask in his beams. Feel his all-seeing eye settled on you in love. And repose in his almighty arms."

This was the basic strategy in the pursuit of holiness. And he knew that the battle would have to be waged all the way to the end. He said to his people, "When a soul comes to . . . Christ, it is not made perfectly holy all at once. 'The path of the just is as the shining light, that shineth more and more unto the perfect day [Proverbs 4:18].'" He was often distressed by his own lack of holiness. But he knew that the battle would be won only in the gospel way of looking ten times to Jesus and "being transformed into the same image from one degree of glory to another" (2 Corinthians 3:18).

So when McCheyne spoke what are probably his most famous words, "The greatest need of my people is my own holiness," he meant not only that they need a pastor who is morally upright, but that they need a pastor who is walking in constant communion with Christ, and being changed into Christ's likeness by that constant fellowship.
