You're waiting for little things like coffee or a stop light. Or you're waiting for huge things like a degree or a proposal.
The whole art of the Christian life is one of waiting - waiting for Christ to return and waiting for Him to restore this broken world.
That's why it makes perfect sense for Christians to be called to patience (Gal. 5:22-23). We glorify God in our waiting by practicing patience. And it sounds easy. But more often than not, it's incredibly painful.
Patience isn't patience unless you have to overcome frustration (or disappointment) to adopt a new heart attitude.
That means killing the selfishness inside of you. Killing takes work. Killing means mess. Killing requires somebody (or something) to get hurt. Patience is war, war against what we'd like to be and what we are.
It's a virtue in the deepest sense. Selfishness and impatience are vices. They rot inside us, staining our good deeds and even stunting our sanctification.
But patience makes us better. Patience is soul-reviving, joy-giving, selfless and holy. It is embracing the divine reminder that God is in control and we are not.
So the next time you want to scream in impatience and that annoying little refrain, "Patience is a virtue" plays in your brain, stop. And believe it. And pray.
