When you meet someone, what's the normal question you ask? 'What do you do?' Instead the religious leaders ask John, Who are you?
1. Why that question? Because the religious leaders notice what John says and does especially against them at risk to Johns life (take a few min to read Matt 3:1-10) Are we as Christians willing to declare Jesus and His truth no matter what the opinion of others around us?
2. Who are you? The next logical question which needs to be asked as it was of John the Baptist is... Who are you? John answered it in light of Jesus. How do we do the same? We must live our lives in light of Him.
I spent a few days in DC with my family a month and a half ago staying with a family who had a dog. It was intriguing to watch the dog live his entire day in light of his master. When the master left, it was like the dog was confused and not sure what to do because his master was gone.
That should be our life in light of Jesus. Is it? Can you say like John that your identity is so tied to Jesus (assuming you call yourself a Christian) that you are voice and only that pointing to Jesus - that's who you are?
