What does my heart look like?

This morning I read 1 Peter 3. In this chapter Peter warns women especially not to worry about their appearance but to behave in a godly manner. He even suggest that when women do this their non-believing husbands will change their minds and believe. I know this is my simple way of looking at it but nevertheless, this is how I read it.
While thinking and praying about this I believe God showed me a picture of an x-ray where you could  see the heart. 
This reminded me of the story in the Old Testament when David was anointed by Samuel. It says in this passage that 'man looks at the outward appearance but God looks at the heart.'
In our Church at the moment we are thinking about having a heartbeat for Jesus. This all ties in with this picture. Are we so worried about all the outward stuff that we forget about the important things? We don't need to worry about what we wear, or how much money we have, or whether we drive a nice car, or even if people like us. We need to worry about if we have a heart that follows Jesus. We need to remind ourselves that Jesus is the reason for all of the stuff we do. We don't need to try and do lot's of things for God to prove that we are a Christian, instead we need to spend time with God, follow the promptings of the Holy Spirit and love others, seeing them through the eyes of Jesus.
Lord help me have a heart beat for you today. Help me not to worry about the outward stuff, but instead to look to you.
