One of the first problems with these type of sayings is that they focus on what we do. If we are have the attitude that we are out to change the world with out even checkin' in with the creator of the world, we take on a monumental task that usually ends in failure. Life is so much simpler when we trust God. Trusting God is not a passive, inactive mind set. Actually it is very proactive, but not in the self-energizing category.
It is easy to tell from which mind set a person is coming from. Check out who gets the glory. When God gives us answers to things, He nails it! You can't help but get excited! The results are easy! The only reason we have difficulty is when we worry, push too much, and doubt. Don't get me wrong. Life is work, no doubt about it, but when we trust Him step by step it is like sailing. Yes we have to adjust the sails and turn the rudder. There is absolutely nothing passive about trusting God. it all hinges on doing this:
5 Trust in the Lord with all thine heart; and lean not unto thine own understanding. 6 In all thy ways acknowledge him, and he shall direct thy paths. (Proverbs 3:5-6)
