Trust

Trust God, not your own bright ideas. It's in the Bible, Proverbs 3:5-6, NIV. "Trust in the Lord with all your heart and lean not on your own understanding; in all your ways acknowledge Him, and He will make your paths straight."

Trust is believing God will do exactly what He says He will do. It's in the Bible, Romans 3:21-22, TLB. "But now God has shown us a different way to heaven—not by 'being good enough' and trying to keep His laws, but by a new way (though not new, really, for the Scriptures told about it long ago). Now God says He will accept and acquit us—declare us 'not guilty’—if we trust Jesus Christ to take away our sins. And we all can be saved in this same way, by coming to Christ, no matter who we are or what we have been like."

Perfect peace results from trusting in God. It's in the Bible, Isaiah 26:3, NIV. "You will keep in perfect peace him whose mind is steadfast, because he trust in You."
