Have you ever asked yourself what's important to me? What was your response? Common responses are financial security. Nice home in a safe neighborhood. These are not necessarily bad things unless you make idols out of them. How often have you asked yourself what is important to God? I mean you say your life is not your own but God's. So how often do you ask yourself what is important to God? Or is your life about you?
The goal of the Christian life is to mesh what's important to you with what is important to God. If we as Christians can accomplish this we can be the light of the world that we are ultimately called to be. I can tell you what was important to Jesus and that was to do the will of the one who sent him.
We have been sent. The question becomes is doing the will of the one who sent us important to us?
