If I was to describe [a believer] from the Scripture character, I should say, he is one whose heart is athirst for God, for his glory, his image, his presence; his affections are fixed upon an unseen Savior; his treasures, and consequently his thoughts, are on high, beyond the bounds of sense. Having experienced much forgiveness, he is full of bowels of mercy to all around; and having been often deceived by his own heart, he dares trust it no more, but lives by faith in the Son of God, for wisdom, righteousness, and sanctification, and derives from him grace for grace; sensible that without him he has not sufficiency even to think a good thought.
But was I to describe him from experience, especially at some times, how different would the picture be? Though he knows that communion with God is his highest privilege, he too seldom finds it so...He takes up the Bible, conscious that it is the fountain of life and true comfort; yet perhaps, while he is making the reflection, he feeds a secret distaste, which prompts him to lay it down, and give his preference to a newspaper. He needs not to be told of the vanity and uncertainty of all beneath the sun; and yet is almost as much elated or cast down by a trifle, as those who have their portion in this world. He believes that all things shall work together for his good, and that the most high God appoints, adjusts, and overrules all his concerns; yet he feels the risings of fear, anxiety, and displeasure, as though the contrary was true.
How can these things be, or why are they permitted?...By these exercises he teaches us more truly to know and feel the utter depravity and corruption of our whole nature, that we are indeed defiled in every part. His method of salvation is likewise hereby exceedingly endeared to us: we see that it is and must be of grace, wholly of grace; and that the Lord Jesus Christ, and his perfect righteousness is and must be our all in all.
