How about idolatry? Why put your faith in something other than God? Tullian Tchividjian writes that "we habitually look to something or someone smaller than Jesus for the things we crave and need. And none of it is ever large enough to fill the void."
How about worry? Why not, as Martin Luther advises, "Call upon God's name in every trouble, pray, praise and give thanks."
How about a favorite hobby? Especially if it get in the way of worshiping faithfully each Sunday.
How about complaining? Who gets under your skin? Your boss, your coach, your spouse, your parents? Give them a break! What seems like an attempt to get in your way may be a loving concern for you, your life and your plans.
How about anger? Anger will try the evict the peace that God has placed in your heart every time. God says, "It is mine to avenge, I will repay."
How about lust? There's temptation sitting at that computer, searching for the latest Kim Kardashian attempt to blow up the internet. Give up the internet instead.
How about deception? The Bible is full of people who tried to deceive others to get what they wanted. Don't join the list.
How about gossip? How about using the season of Lent to practice this: "Defend (your neighbor), speak well of him, and explain everything in the kindest way."(Thank you, Dr. Luther) You think people might notice the difference between you and others who can't wait to share half-truths or tear reputations apart with tongues of fire?
How about dissatisfaction? Yeah, somebody may have stuff that's better than your stuff. But your stuff is better than the stuff that most people in the world have. Praise God for the stuff you got.
