Christians and God

We live our lives as if there is no God.  Christians, however, use the idea of God, or claim there truly is a God when it is convenient for them.  Christians act like there is no God.  Here are some examples:

1. Christians buy car insurance.
2. Churches have property insurance.
3. Christian cops wear bullet-proof vests.
4. Christians wear seat-belts.
5. Christians get their kids immunized.
6. Christians pass laws to get some of the above made mandatory, to help their fellow Christians.
7. Some church buildings have lightning rods (lol ironic).
8. Christians hire private investigators.

If there were a God, none of these would be necessary.

I don't believe many Christians actually believe in God - but use Him as a tool, or sometimes a weapon.  They hope there's a God, but don't really believe.  Someone prove to me how I'm wrong.
