Psalm 4:8

I will both lay me down in peace, and sleep: for thou, Lord only makest me dwell in safety.

When we have sleepless nights, it means somehow; we don’t feel safe.  Our peace has been stolen, and we have a problem that we don’t think we have an answer.  Pull out the sword (bible) and find the scripture that covers the issue, pray, and remind the devil we have the answer.  Don’t try to figure out the how, but just pray and turn it over to God.
