"Mix not...foundation and building work together. Our foundation in dealing with God is Christ alone, mere grace and pardon in him. Our building is in and by holiness and obedience, as the fruits of that faith...But doth this not tend to licentiousness? doth not this render obedience, holiness, duties, mortification of sin, and good works needless? God forbid; yea, this is the only way to order them aright unto the glory of God. Have we nothing to do but lay the foundation? Yes; all our days we are to build upon it, when it is surely and firmly laid...First...take up mercy, pardon, and forgiveness absolutely on the account of Christ, and then...yield all obedience in the strength of Christ and for the love of Christ...[this] is the life of a believer, Eph. ii. 8-10."
