Let's face it, watching another person live their life is a lot safer than actually living our own life. We don't have to worry about the hurt of rejection or the pain of failure. Being life voyeurs is a relative safe thing to be.
Think about what Jesus said to his disciples before he ascended into heaven:
Jesus came and told his disciples, "I have been given all authority in heaven and on earth. Therefore, go and make disciples of all the nations, a baptizing them in the name of the Father and the Son and the Holy Spirit. Teach these new disciples to obey all the commands I have given you. And be sure of this: I am with you always, even to the end of the age" (Matthew 28:18-20, NLT).
There are two truths that I want to point out. First, Jesus makes it clear that he has the authority, and in that authority he is sending us out. We have the authority of God behind us! That should give us the courage and the resolve to live boldly!
Second, is the command to go. Jesus expects his disciples to go into the world. As we go we are to proclaim the Gospel, in both word and deed, to those around us. We cannot follow Jesus and remain on the sidelines.
It is easy to watch other people live life, but that is not the type of life God created us to experience. He created us so that we can join Him in bringing redemption to the world. Now that is a life worth living!
