Return unto thy rest, O my soul; for the LORD hath dealt bountifully with thee.
Psalm 116:7 (KJV)
Our soul returns to its rest when we are confident that God is handling everything that concerns us. We rest in our confidence that God has already made available what we need, and out of this quiet assurance will we see His goodness showing up in our lives. God works when we are at a place of peace.
