Hidden
When looking at an optical illusion, our eyes have to adjust and be at the right distance before we can distinguish the shape behind the various colorful patterned blotches. The picture is always there; it's just unseen until the correct moment of focus. When anything is hidden or out of our direct range of perception, it still exists; it just hasn't been revealed to us. There is no such thing as an unsolved mystery with God. He is all knowing. The Lord will lead us to what he wants us to learn, and he will one day make known what he may presently be hiding (see Deuteronomy 29:29).

It's impossible to hide from God. He sees us when we sin, but he also knows our need for help. When we're in danger, we can go to God for assistance. The Bible illustrates this with an image of us hiding in him, finding shelter, a resting place.

Nothing is hidden from God-not our hearts or our actions.
