Suppose there is someone in your life you trust implicitly. Suppose on every issue you gladly turn to this person for wisdom, counsel, support, encouragement. Suppose this person loves you, has your best interest and God's glory in mind. Suppose in every direction, whichever way you look at it, this person takes the proverbial cake. Except in one area. Say it's that they cannot bake a good cookie. This person repeatedly disappoints you, continually confuses you, and surprises you every time with how lousy their chocolate chip cookies turn out. No matter how you look at it you cannot make sense of this one small area.
Now, suppose that God asks you to trust Him beyond how you trust this person, and in spite of their continual failings in this area. Suppose that God says, "I know this person cannot be counted upon to make a perfect chocolate chip cookie, they continually forget necessary ingredients, and almost always burn the cookies, but that's okay, trust Me, because my faithfulness supersedes theirs and always will. Trust Me."
Now you have a choice: do you trust God (even though you've never actually seen God make a half decent cookie of His own) or do you keep your eyes on this person who, despite this one little thing, has never failed you yet?
That is the question, isn't it?
Some trust in chariots and some in horses, but we trust in the name of the Lord our God. Psalm 20:7
