I missed two successive Lord's Day services due to sloth and sluggishness. I even lied to my pastor about the reasons. I've repented of my lying and of having profaned the Sabbath, and I've confessed to both him and the Lord. In other words, my piety is pathetic. I feel like Peter humiliated by Paul for hypocrisy—and rightly so.
I found this essay by Joel Beeke entitled, "Calvin's Piety." I need the first use of the Law to weigh down on me and the Gospel to remind me of Christ's active and passive obedience (and the imputation of their merits) in order to impel me to walk gratefully in the Law's third use.
"Wretched man that I am! Who will deliver me from this body of death? Thanks be to God through Jesus Christ our Lord! So then, I myself serve the law of God with my mind, but with my flesh I serve the law of sin" (Rom. 7:24-25).
