It means you have little faith in anything other than God.
I think God has given us lots of tools. For example, God gave us doctors and hospitals to help us heal from different afflictions. God also gave us scientists and instruments to help us see his wonderful creation.
Sure men make mistakes, but I still go to the doctors, just like I still trust in Carbon dating that shows how old things are.
I don't think God gave us doctors and hospitals. What we are given is intelligence, with which we can learn not to put our hands on the stove twice, and with which we can teach our children not to do it once.
This is the essence of science. Learning how the world works. What things are useful and what things are harmful. Science is also sharing our discoveries with others and with generations that will live after we are gone. It is organized and systematic love.
