"A small thing is not small when it leads to something great." - St John of Damascus
Jesus said something similar, 700 years before John of Damascus - even if we have faith as small as a tiny mustard seed we can command mountains to move and they will move (Matthew 17:20). God does not despise things that the world may consider insignificant. God can always turn our humble offerings into something awesome.
Bring what you can to God and watch Him perform wonders.
I dare you.
