In the deepest darkest moments of my life, the only thing that would console me was that Jesus knows. He knows it all. He understands things others may only guess at. And He cares. I didn't have much to say for myself during those times. All I recall getting out was 'Oh God. Oh God. Oh God.' But He knows.
If you are going through a dark moment - or perhaps are still walking through a dark valley - then this is for you:
He who dwells in the secret place of the Most High shall abide under the shadow of the Almighty. I will say of the Lord, "He is my refuge and my fortress; my God, in Him I will trust." Psalm 91:1-2
