We learn this through the enlightenment of the Holy Spirit. _210. What is meant by the enlightenment of the Holy Spirit?_ Through the enlightenment of the Holy Spirit our knowledge of the Gospel truths becomes a living and saving knowledge to our hearts. =John 14:26. But the Comforter, the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.= =John 16:13. When he, the Spirit of truth, is come, he will guide you into all truth.= _211. Of what nature is our knowledge of these truths before the Holy Spirit has enlightened our hearts?_ It is a dead knowledge only, which does not lead to repentance and faith, but leaves us in our sins. _212. What is the true and living faith in Jesus Christ?_ This is faith, that a repentant sinner lays hold of Christ as his only Savior from sin, and death, and the power of Satan; That he takes refuge with Christ and His righteousness, and builds thereon with the confidence of his whole heart. _213. Can only a repentant sinner have this faith in Christ?_ Yes; the faith which lays hold of Christ and His righteousness, can be wrought in that heart only which bitterly feels the pain and misery of living in sin. =Matt. 9:12. They that be whole need not a physician, but they that are sick.= _214. Is the true and living faith always and in all persons equally strong?_ No; it is often very weak and scarcely able to avail itself of the grace of God. =Mark 9:24. Lord, I believe; help thou my unbelief.= _215. Whereby may we know whether this weak faith is true and living?_ The true and living faith is known by an earnest hatred of sin, and an eager longing for grace. _216. Does God accept this weak faith?_ Yes, indeed; only it be true and sincere. =Isa. 42:3. A bruised reed shall he not break, and the smoking flax shall he not quench.= _217. What benefit do we have from the true and living faith in Jesus Christ?_ By faith we are justified, born anew, sanctified, and finally saved forever. _218. What is Justification?_ Justification is the gracious act of God whereby He for Christ's sake acquits a repentant and believing sinner of his sin and guilt, and looks upon him, in Christ, as though he had never sinned. =2 Cor. 5:21. For he hath made him to be sin for us, who knew no sin that we might be made the righteousness of God in him.= =Rom. 3:24. (They are) justified freely by his grace through the redemption that is in Christ Jesus.= _219. What, then, does the believer receive through justification?_ He receives the forgiveness of sins, and is adopted as a child of God. =Eph. 1:7. In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace.=
