"Listen to how someone prays -- it will reveal what they really think about Jesus. Does he sound near, or does the prayer make him seem far away, up above the sky somewhere? Does it sound as though Jesus might be someone we are bothering with our requests, someone with far more important things to do? Does he have a sense of humor, or is he always serious? Is it formal, and religious, or "Good morning, Papa"? Do they even sound like they know him? Really, listen to their prayers. Listen to your own."
I think it would be interesting to practice praying out loud while recording it on your smart phone. Then wait a week and play the recording back. Maybe it would be better to have someone else listen to it and give you their honest opinion about what you really think about Jesus.
Then try this; try talking to your best friend the same way you talk to God. How would that go over?! My guess is that for the vast majority of us, our best friends would begin to dread the times when you get together to talk. Give it a try!
