Our salvation, calling and good works in life are all founded on, motivated and empowered by the grace of God working in us. Christ's Gospel work -His Life, Death and Resurrection- is what secured this grace in the past and ensures it forevermore in the future. We must depend by faith on the continual arrival of this grace moment by moment in order to walk with God in a pleasing way and accomplish the works that he has given us to do for his glory.
