Faith is...
Waiting on God, when the only thing you desire is to get involved and "take care of it" by yourself.
Resting in God, when everything in you wants to take control and keep saying or doing until things are better or how you think they should be.
Seeking the Lord in prayer, instead of seeking out friends to complain to or spending time alone worrying.
Leaving it in His, more than capable, hands instead of analyzing the problem to death in your mind to try and fix it.
Worshipping and trusting in our Lord and Saviour.
