But perfect trust is resting all of one's weight on something else, not on self. It's like resting on crutches to hold you up when you twist an ankle. You lean on them as your strength.

Strength comes from choosing to fully trust, pray, and praise.

Then, he will make the trial a blessing, teaching me lessons He intends for me to learn, and working in me the grace He means to bestow. Last, in His good time, He can bring me out again-how and when, He knows. But this peace isn't a nirvana hypnotic trance or something encountered by repeating a mantra a thousand times.
