Assurance
Whom God legally saves, He experimentally saves; whom He justifies, them He also sanctifies. Where the righteousness of Christ is imputed to an individual, a principle of holiness is imparted to him; the former can only be ascertained by the latter. It is impossible to obtain a Scriptural knowledge that the merits of Christ’s finished work are reckoned to my account, except by proving that the efficacy of the Holy Spirit’s work is evident in my soul.
It is only in proportion as the Christian manifests the fruit of a genuine conversion that he is entitled to regard himself and be regarded by others as one of the called and elect of God. It is just in proportion as we add to our faith the other Christian graces that we have solid ground on which to rest in the assurance we belong to the family of Christ. It is not those who are governed by self-will, but “as many as are led by the Spirit of God, they are the sons of God” (Rom. 8:14).
