We must not trust ourselves over God

He who dwells in the shelter of the Most High will abide in the shadow of the Almighty. I will say to the Lord, “My refuge and my fortress, my God, in whom I trust.” (Psalm 91:1, 2 ESV)

There are days when it feels like we should trust in ourselves, when every fiber in our being seems to whisper "I'm in control".  This is an illusion, a sin of pride.  We must abide in the shadow of the most high and seek not to trust ourselves over Him.
