=1 Peter 1:23. Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth forever.= _227. Is the New Birth necessary to our salvation?_ Yes, indeed; except a man be born anew, he cannot see the kingdom of God. John 3: 3. [R. V.] =John 3:6. That which is born of the flesh is flesh; and that which is born of the Spirit, is spirit.= _228. What does the Holy Spirit further work in the believer?_ He sanctifies and preserves him. _229. What is Sanctification?_ Sanctification is the gracious work of the Holy Spirit whereby He day by day renews the believer more and more after the image of God. _230. How is the daily renewal accomplished?_ The old man, or sin, is put away more and more, and the new man, or the new spiritual life, appears more and more in all our conduct. =Eph. 4:22-24. [R. V.] Put away, as concerning your former manner of life, the old man, which waxeth corrupt after the lusts of deceit;= =And be ye renewed in the spirit of your mind,= =And put on the new man, which after God hath been created in righteousness and holiness of truth.= _231. How does this new conduct appear in the daily life of a Christian?_ A Christian denies himself, strives against the devil, the world, and his own flesh; he grows in love toward God and man, and seeks to do the will of God in all things. =Matt. 16:24. If any man will come after me, let him deny himself, and take up his cross, and follow me.= =1 Cor. 16:13. Watch ye, stand fast in the faith, quit you like men, be strong.= =1 Tim. 6:12. Fight the good fight of faith, lay hold on eternal life, whereunto thou art also called, and hast professed a good profession before many witnesses.= _232. Is the believer, then, justified and saved by his own good works?_ No; our best works avail nothing to this end: we must build our hope of salvation on Christ alone and His righteousness. =Luk. 17:10. When ye shall have done all these things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do.= _233. What is the work of Preservation done by the Holy Spirit?_ Preservation is the gracious work of the Holy Spirit whereby He keeps us, through all temptations, in the true and living faith in Jesus, until the end. =Phil. 1:6. [R. V.] He which began a good work in you will perfect it until the day of Jesus Christ.= _234. By what means does the Holy Spirit sanctify and preserve the believer?_ By the Word of God and the Lord's Supper. _235. How does the Holy Spirit preserve the believer?_ He teaches and guides, corrects and comforts him. _236. What are they called whom the Holy Spirit thus sanctifies and preserves in faith?_
