The term Butterfly Effect refers to how a 'small change in one place can cause bigger changes in another place.' It can be used in all kinds of contexts, but I think that Scripture speaks of a similar thing when we are encouraged to have faith - even if it is as small as a mustard seed.
Jesus said that if we had faith (as small as a tiny seed), we could impact a mountain far away.
Why don't we allow God to take our small acts of faith today - and multiply them for his Glory.
Small changes now will bring HUGE changes later.
