Same Full and Abundant Benefit
But it is the same full and abundant benefit of forgiveness that is offered in the Word, received by faith, and signed and sealed by the sacraments of baptism and the Lord’s Supper. In this benefit it comes out clearly that the sacrament does not add a single new grace to the Word; with an eye to our weakness, it only bestows the same grace in another manner in order that we may firmly believe and be healed of all doubt.
