I can trust God fully with my life because He promises to take care of me, and to be the Source of my hope. This is a promose to which I can (and do) cling – remembering that the Lord has a plan in place for my life, and that these “plans for good” are already unfolding in time and history, according to the Lord’s timing.
Of course, how the Lord defines “good” may be different than my take on it, but His view on any matter is always best. Not easy, mind you, but best. 🙂
