1. Are all justified persons also sanctified?

Yes, justification and sanctification are inseparable.
"But of Him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption"(I Cor. 1:30;cf. Ps. 130:4).

2. What is sanctification?

A renewing of the whole man.

3. Is sanctification only a change in outward actions?

No, but also a change of the inward man. "Be ye transformed by the renewing of your mind" (Rom. 12:1).

4. Does external change flow from sanctification?

Yes, sanctification affects all actions of the elect. "The very God of peace sanctify you wholly: and, I pray God, your whole spirit and soul ahd body be preserved blameless" (I Thess. 5:13).

5. Who works sanctification in God's people?

God, by His Spirit (I Cor. 6:11).

6. Is sanctification necessary in this life?

Yes. "Follow peace with all men, and holiness, without which no man shall see the Lord" (Heb. 12:14).

7. Is sanctification perfect in this life?

No, it is only partial and imperfect. "Not as though I had already attained either were already perfect" (Phil. 3:12).

8. Is sanctification equal in all believers?

No, sanctification varies in its degrees; it is manifest in one more than the other.

9. Does sanctification vary within the believer?

Yes, it is subject to increase and decrease in the individual believer.

10. Can sanctification be totally lost after it is begun in a believer?

No, where the grace of God begins to work sanctification, it will also continue to work it.

11. Is there such a thing as the apostasy of the saints?

No, they may fall into sin on specific occasions, but they will never fully apostasize from the state of grace. "Who are kept by the power of God, through faith unto salvation, ready to be revealed in the last time" (I Pet. 1:5).

12. How can God's children advance in sanctification?

They must use all means which are conducive to advancement in holiness and must seek to rid themselves of all internal and external obstacles to such advancement. This is only possible if their sole reliance is upon the power of Christ and the grace of the Holy Ghost.

13. What are the fruits of faith and sanctification?

Good works. "Yea, a man may say, Thou hast faith, and I have works; shew me thy faith without thy works, and I will shew thee my faith by my works" (James 1:18).

14. What are good works?

Acts that are performed: (1) in faith; (2) according to the law of God; and (3) to the glory of God.

15. How can we prove that a good work must be done in faith?

From Hebrews 11:6, "Without faith it is impossible to please God."

16. How can we prove that a good work must be performed according to the law of God?

From Matthew 15:9, "In vain they do worship Me, teaching for doctrines the commandments of men."

17. How can we prove that a good work must be directed to God's glory?

From I Corinthians 10:31, "Whether therefore ye eat or drink, or whatsoever ye do, do all to the glory of God."

18. Must we do good works?

Yes. "Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven" (Matt. 5:16).

19. Can our good works merit heaven?

No. Christ alone hath merited that for us.

20. Why do not our good works merit heaven?

Because all our works are imperfect. "And all our righteousnesses are as filthy rags" (Isa. 64:6).

21. Why must we perform good works if we cannot merit salvation by them?

(1) To glorify God; (2) To edify our neighbors; (3) to assure ourselves of our faith.
