Why a teaching series on pride, greed, envy, sloth, lust, gluttony, and wrath?
For the same reason we study cancer, opposing armies, and the other team’s play-calling tendencies. We’re studying sin to identify it in our hearts, name it, and kill it.
We’re studying these sins for our joy. Sin is soul-hollowing, boring, deadening, and at the end of the day, a killjoy. The life of Christlikeness is joyful. It’s human life as it ought to be. It honors God and opens us up to God’s own eternal joy. Why wouldn’t we want to labor against these besetting sins to grow in our joy in Christ?
