Look to Jesus.
If you are happy and hopeful, brimming with excitement and eagerness for the day, look to Jesus.
If you are discouraged and empty, tired and heartsick, look to Jesus.
If you are grieving and lonely, look to Jesus.
If you are frustrated and angry already, look to Jesus.
If you're busy, look to Jesus.
If you're resting, look to Jesus.
If you're at school or work and you don't want to be (or maybe you do), look to Jesus.
He will make you happy, complete, encouraged, hopeful, peaceful, comforted, and loved. Take your eyes off of yourself. Stop complaining. Stop self-pitying. Stop believing what you feel. Stop looking elsewhere for joy. Stop trusting in yourself. Stop trusting in circumstances.
And look to Jesus. That's the best possible thing you can do today.
