What's my excuse?

At BSU on Thursday night, the speaker talked about worship. His message was about how worship is a choice and not a feeling. It's hard to worship when we're not in the mood or when we're tired or when we don't like the song choice. But since when is worship about us?! Worship is about giving praise to God, not about making us comfortable. The speaker shared with us about a man who was paralyzed and in a wheelchair. He told us that the man went to Afghanistan with his parents and at first wasn't too happy about it. But, because of his wheelchair, he had an amazing chance to share the gospel with a group of kids playing soccer. He got up on stage and shared with a group of people about his experience in Afghanistan. When he was done with the story he looked out at the crowd and said "You look at me in my wheelchair and feel sorry for me, but because of my wheelchair, I had an opportunity to share the gospel." Then he pointed into the crowd and said, "WHAT'S YOUR EXCUSE?!" Pretty convicting, huh? God has used that story to challenge me to be bold in my faith. Because, seriously, why am I not sharing my faith? What's my excuse?
