Discomfort is: A state of mental uneasy, worry, or embarrassment.
There is a YouTube channel that I have been following recently where people are always trying to be in a state of discomfort. They seek an uncomfortable lifestyle, the theory is that we are too comfortable and need to say yes to more spontaneous things and seek discomfort for us to grow as people. They live by this theory by doing simple things like trying to find a stranger to go skydiving with them, or getting matching tattoos with with complete strangers.
To some extent I believe that we should be more willing to do things that make us uncomfortable in everyday life, but these people are just searching for something to fulfill them.
However, this lifestyle can be applied to our Christian walk. When is the last time you did something that required an uncomfortable step in faith? This could be anything from sharing the gospel with someone you work with or maybe a complete stranger. Maybe it looks like going on a mission trip to a third world country and leaving the comforts of our life behind. If you talk to people who do these things often you hear them say: "I felt like I was blessed so much more then the people I was there to bless."
Without discomfort there is no room to grow. Even humans have growing pains as they grow from a child to an adult. I think one of the most best examples of this is Peter walking on water.
Take a minute and go read Matthew 14:22-33.
Peter is someone who would have been well aware of the dangers of getting out of the boat during a storm after spending his life on the water. But Peter was willing to be uncomfortable to be closer to Christ. I have a feeling Peter was in a state of mental uneasy, worry, or embarrassment. But he had his eyes on Christ. Are you willing to get uncomfortable to serve Christ? Peter ended up taking his eyes of Christ and he sunk, Jesus saved him and said, "You of little faith, why did you doubt." What would Jesus have said if Peter never took his eyes off of Him?
My challenge to you is to find something in your life that God is calling you to do that makes you uncomfortable and do it. It might be weird or you might be worried you will be embarrassed, it might even be awkward, but there is awesome in the awkward.
