When the night brings thoughts of demise and similar forms of dread I prepared a sheet of "Night Verses" hoping to order my subconscious into a more optimistic light.
These verses were normally oriented toward healing. Not all verses are as powerful and so prominently important. I think they work quite well, if I could only learn to consult them more often. This especially since answers and direction often spring into my conscious at unexpected times.
"Surely he has borne our griefs and sickness, and carried our sorrows and pains; yet we did esteem him stricken, smitten of God, and afflicted. But he was wounded for our transgressions, he was bruised for our inequities: the chastisement of our peace was upon him; and with his stripes we are healed." Isaiah 53:4-5
The only way to gain faith given in the Bible is to read and reread until faith is driven deep down into our subconscious.
