Read: Luke 9:1-6
And he called the twelve together and gave them power and authority over all demons and to cure diseases, and he sent them out to proclaim the kingdom of God and to heal. (Luke 9:1, 2 ESV)
Jesus gave them power and authority. The disciples became his ambassadors. They became his representatives everywhere they went. Not just in name either. He gave them authority, but also the power to back it up.
Everywhere that these men were to go they were to boldly proclaim the truth of the gospel. And then to demonstrate that truth they were commanded to perform miracles. They would say something, and then they would do something that would demonstrate the legitimacy of their statements.
When we speak of Jesus do we offer action that shows the truth of our convictions? Shouldn't we? Christianity is not just about checking off a list of beliefs. It is also more than just running out and acting out of altruism. The Christ followers life is a balance of both. It is about proclamation and demonstration. It is saying and doing.
To fully embrace life as a disciple of Jesus is to embrace the power and authority Jesus gives us. That means saying who Jesus is to you, and then demonstrating the same thing.
