Our lives always have to be held in the hands of God and trust Him all the time, because He is our shield, our keeper.
God is the one who sustains us in times of crisis and darkness, He is the one who takes care of us so that we do not fall into an emptiness from where we can not leave with our own strength, and this is because the Lord helps us to get out of everything that is difficult that we find on the road.
You, Lord, keep my lamp burning;
my God turns my darkness into light.
He is the one who gives us light in the midst of darkness, and in shadow valleys keeps us from all evil. When the evil one wants to attack us He warns us to prepare ourselves.
