My name is written on your hand

I've recently downloaded the new Tim Hughes album from iTunes and I have been listening to 'Counting on Your Name' which I first heard at the New Wine conference in the summer.
It starts with the line: 'My name is written on your hand, you've called me your own.' The image that conjures up is amazing - to be so loved by God that you are His only priority or concern, to have such a deep relationship with Him, is unimaginable.
God loves us so much, we only have to remember Christ's death on the cross to know this. But what do we do with this love? We forget it - we make idols out of our lives and the things that concern us: careers, families, possessions. These things need to be given over to God, not so we can do without but so we can show our complete trust in Him; He loves us and does not want us to go without unnecessarily but when we trust in Him we get everything we would ever need.
Paul writes to the Philippians that he has learned to be content (4:11) and I have been studying this very idea in my personal Bible study. I am rather content with my life, I couldn't really ask for a better one and I know I am very lucky for the things I do have. What I wonder about is do I really 'count on his name'? Do I rely on Him for everything or just when I need help and comfort? Do I think more about my own needs rather than those around me?
We are so loved so that we can share that love with others - not in an airy fairy way but in real practical ways. Worship should lead us to really act and love others, not just being thankful that we are that important to God.
