Psalm 23:4 KJV
I will fear no evil: for thou art with me; thy rod and thy staff they comfort me.
Promise #269: When you walk through the valley of the shadow of death, I will be with you.
However, I do want to ask you to think of another application of this promise… Jesus told us that except a seed falls in the ground and dies, it abides alone (John 12:24). The principle of the Christian life is a continual letting go of things, allowing them to ‘die’, only to see them resurrected again by the power of the Holy Spirit. Whether those things are dreams or desires, the principle of the cross (death, burial, resurrection) is a resounding theme in the daily Christian life.
In that context, when you are feeling like God is asking you to surrender something dear to you, when you are in a sense walking through the shadow of death for something that you have hoped for, be comforted in knowing that God is very close to you in those times of surrender and His staff and rod will bring comfort to you. Weeping may endure for the night, but joy is coming in the morning! (Psalm 30:5)
