Some theologians divide transgressions into “sins of the flesh” and “sins of the spirit.” This means that some sins originate in our physical passions; others come from our “heart” or disposition. In the story of the prodigal son, the elder brother’s attitude gives us an example of the latter.

We’re inclined to single out the prodigal son as worse than his brother. But it’s worth noting that when the story ends, the prodigal is restored, forgiven, and full of joy, while the elder brother stands outside and refuses to go in.

The stay-at-home son is more than background filler. He makes us think about the state of our heart, for sour moods create untold misery.

Discontent, jealousy, bitterness, resentment, defensiveness, touchiness, and ingratitude are the dispositions that ruin our marriages, wither our children, alienate our friends, and embitter every life—including our own.

It’s easy to defend our bad moods and to slide into deception and hypocrisy. But we must guard our hearts against such destructive attitudes. When they arise, we need to confess them, let them go, and experience God’s forgiveness.

Don’t let your bad attitude cause you to lose out while others enter into joy.  — David H. Roper
