One of the first verses I studied in the Bible was this:
For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.
It gave me so much hope because I had nothing but fear! And I wanted nothing more than to have a sound mind.
It took a while to figure out that it was God I needed to put my trust in, when all the while I’d put my trust in men and institutions who claimed to know Him. I came to know Him, personally. And that gave me peace.
I will both lay me down in peace, and sleep: for thou, LORD, only makest me dwell in safety.
Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee.
Have a sweet sleep!
