Grace takes away guilt; mercy, misery: peace implies the abiding in grace and mercy. It includes the testimony of God's Spirit, both that we are his children, and that all our ways are acceptable to him. This is the very foretaste of heaven itself, where it is perfected. In truth and love — Or, faith and love, as St. Paul speaks. Faith and truth are here synonymous terms.
