Once given those instructions they go back to the basics and complete what they do know. It's amazing to watch how just completing a few steps of any given problem with what they know somehow helps the bigger problem at hand to not seem so overwhelming and impossible.
When encountering such a circumstance more recently I heard a gentle whisper flow through my spirit in encouragement and direction, "Start with what you know."
So I did. I went back to all I have learned and know God to be. I used my experiences, knowledge of His Word and understanding to get me started down the path of trusting and believing that He does all things well, that He works all things for good to those that love Him.
I encourage you to give it a try. Next time you are faced with something that seems much too complicated, unexplainable, irrational, or just too much to begin to even know where to start in processing it all.... just start with what you know.
It really is a good place to begin.
