I found a wonderful book recently through Grace and Truth Books (a favorite web book seller!) called Voices from the Past with short-but-powerful daily readings from a variety of Puritan authors.
Today's reading blessed me deeply as I face major surgery at the Mayo Clinic next week. I'm clinging to God tightly and the words below encouraged me. Perhaps they will comfort or challenge you.
"God is the happiness of man because of His suitableness to the soul...Tasting this manna tramples on the onions of Egypt. God is true happiness of the soul because He is an eternal good. As the sun never sets, so the soul that rests in God has an eternal Sabbath...This all-sufficient, suitable, and eternal God is the saint's peculiar portion, and therefore causes infinite satisfaction. God is my portion forever...The pronoun 'my' is worth so much to the soul. Luther said much religion lies in the pronouns. All our consolation indeed consists in this pronoun. He is my God. All the joys of the believer are hung upon this one string. Break this and all is lost. I have sometimes thought how David rolls this word as a lump of sugar under his tongue: 'I love you, O Lord, my strength. The Lord is my rock and my fortress and my deliverer, my God, my rock, in whom I take refuge, my shield, and the horn of my salvation, my stronghold' (Psalm 18:1-2).
