“Learn much of your own heart; and when you have learned all you can, remember you have seen but a few yards into a pit that is unfathomable.
‘The heart is deceitful above all things, and desperately wicked: who can know it?’ Jeremiah 17:9.
Learn much of the Lord Jesus. For every look at yourself, take ten looks at Christ. He is altogether lovely. Such infinite majesty, and yet such meekness and grace, and all for sinners, even the chief!
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.
Cry after divine knowledge, and lift up your voice for understanding. Seek her as silver, and search for her as for hid treasure, according to the word in Proverbs 2:4.
See that Proverbs 2:10 be fulfilled in you. Let wisdom enter into your hearts, and knowledge be pleasant to thy soul; so you will be delivered from the snares mentioned in the following verses.
Let your soul be filled with a heart-ravishing sense of the sweetness and excellency of Christ and all that is in Him.
Let the Holy Spirit fill every chamber of your heart; and so there will be no room for folly, or the world, or Satan, or the flesh.
I must now commend you all to God and the word of His grace. My dear people are just assembled for worship.
Alas! I cannot preach to them tonight. I can only carry them and you on my heart to the throne of grace. Write me soon.
Robert Murray M’Cheyne”
