Yes, very important, most important, which is why I say this following the fifth point of the kerygma elaboration:
5. Then God’s Holy Spirit will establish a saving relationship with those who freely accept Him (RV 3:20) that will eventually achieve heaven when by means of persevering in learning Truth/God’s Word/sanctification everyone cooperates fully with His will (JN 14:6, 17&26, RM 8:6-17, GL 6:7-9, EPH 1:13-14, HB 10:36, 12:1, JM 1:2-4).
Although perfection is not achieved in this life, the necessity of learning the didache in order to strive for perfection indicates the need for perseverance or to keep on learning and growing spiritually until we die physically (PHP 3:12-14). Thus, although learning any specific part of the didache is not GRFS, a person who does not “hunger and thirst for righteousness” (MT 5:6) or want to learn “every word that comes from the mouth of God” (MT 4:4) fails the self-examination Paul commanded and Jesus implied (mentioned previously).
If we truly believe in Jesus as Christ, the One who represents God the Father, then we will also accept Him as Lord (LK 2:11) or God the Son (MT 16:16) or God in the human dimension (CL 2:9). When we truly accept Jesus as Lord, we will want to please Him by doing His will (MT 7:21, EPH 5:8-10). Learning the manifold teachings or doctrines describing God’s moral will takes a lifetime. Thus, the need for perseverance/loyalty/remaining faithful, which is as easy or simple as an act of will. Remain faithful until the end.
Paul taught the importance of continuing to learn God’s Word (LGW) in 2TM 3:14-17, saying “Continue in what you have learned and have been convinced of, because you know those from whom you learned it, and how from infancy you have known the Holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work.”
Paul explained how LGW may be accomplished in EPH 4:11-13: “Christ himself gave the apostles, the prophets, the evangelists, the pastors and teachers to equip his people for works of service, so that the body of Christ may be built up until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ.” For those able to obtain a Bible (thanks to the invention of the printing press), much can be learned simply by reading it. It makes sense to start with a gospel, next read an epistle such as Ephesians, then Genesis to begin providing OT context for the NT Gospel, followed by Acts and Hebrews to learn how the church superseded the Torah. Romans 1&2 (creation and conscience) indicate how souls who had no opportunity to learn Scripture may be saved (called general revelation), Revelation describes the ultimate destiny of souls, and 1CR 15:14 admits that if Christ is not raised, then LGW about how to be saved is useless.
Part II: Need for Perseverance
The fifth point of the creed set forth in Part I warrants additional explanation. Just as unsaved sinners do not experience complete hell on earth, saved sinners/saints do not “live happily ever” on this earth when they repent of evil/Satanism. While we look forward to the proverbial “pie in the sky by and by”, we receive only a taste of heaven (HB 6:5) in the here and now. In order not to become discouraged, Christians need to understand that salvation has three stages or time components. They were saved from ultimate hell at the moment of deciding to accept Jesus as Lord (EPH 1:13, RV 3:20), they are (being) saved or perfected morally while remaining loyal to Jesus (JM 1:3-4), and they will be saved bodily on the day of resurrection (ZCH 14:1-9, 1THS 4:16, cf. 1CR 15:35-55).
The spiritual union between believers and Christ is comparable to marriage (EPH 5:23-32), and just as a husband and wife need to continue their commitment until they part at death, Christians also need to retain saving faith (LK 9:23, 2CR 4:16) as they grow spiritually, learning how to become more like Christ or achieve His fullness. Then they will neither take God’s grace for granted nor repent of their decision to serve Him as Lord. In other words, perseverance is an implicit and integral part of faith; Christians need to persevere in their acceptance of the kerygma and to keep on learning the didache until the day they die (MT 10:22, 2THS 1:3-5, 2PT 1:5-8).
Saying we “need” perseverance prompts this question: Is it possible for a Christian to repudiate his/her saving faith and become apostate or again bound for hell? Before seeking to answer this question, we should remember that although perseverance is an implicit part of the creed, understanding the details of this or any doctrine is not necessary in order to remain saved, because the kerygma is simple enough for a young soul to understand (cf. MT 18:3), and didachaic details can become rather complicated and controversial. Thus, a Christian needs to be humble or Spirit-filled before tackling such issues, keeping in mind that whichever position a Christian takes on any secondary doctrine, he/she should fellowship with those having a different interpretation who affirm the kerygma both verbally and by typically manifesting divine love.
The issue of apostasy has been debated ever since Augustine of Hippo developed his doctrine of predestination about A.D. 400. Romans 8:38-39 seems to say that it is impossible for a Christian to fail to persevere. Paul writes: “For I am convinced that neither death nor life… nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.” We also read in John 10:27-29 that Jesus said, “My sheep listen to my voice… no one can snatch them out of my Father’s hand.” (Also, see RM 8:38-39, RM 14:4&10, 1CR 1:8, 10:12 & 15:5, 2CR 1:20-24, EPH 1:11-14, 1JN 2:19, PS 135:6 & PR 21:1.)
However, there are numerous verses in the NT which indicate that it is possible for a believer intentionally or willfully to separate him/herself from Christ (cf. GL 5:1 & RV 12:9). The classic passage that teaches the possibility of apostasy is Hebrews 6:4-6: “It is impossible for those who have… shared in the Holy Spirit… if they fall away, to be brought back to repentance, because to their loss they are crucifying the Son of God all over again.” Another verse in this vein is Galatians 5:4: “You who are trying to be justified by law… have fallen away from grace.” (The reader should also see RM 11:22, 1CR 15:2, CL 1:22-23, 2THS 1:4-5, 2TM 2:12, HB 3:6&14, 10:35-36, JM 1:12, 2PT 1:10-11, 2:20, 1JN 2:24-25 and RV 2:10. These Scriptures are quoted at the end of this part.)
Some Christians say that the biblical exhortations to persevere do not imply the possibility of apostasy but this interpretation is problematic for three reasons:
First, the plain sense of many verses of Scripture including those listed in the preceding parentheses suggests that it is possible for a believer to commit apostasy, and saying that this understanding is false seems to make God tricky.
Second, God’s plan of salvation from the miserable consequences of choosing to reject Him makes sense only if people are morally accountable or free, and free will is meaningful only if a person can choose between essentially opposite options, as in Deuteronomy 30:19: “I set before you today life and death, blessings and curses.” This is the same choice that was set before Adam and Eve in the Garden of Eden (GN 2:16-17) and before that to Satan in heaven (LK 10:18). I see no reason to think that this choice is not eternal, because it is this choice which creates: free will (faith in Christ or antichrist), moral responsibility (love the Lord or hate Him) and meaningful life (taste of heaven now and hope for eternal joy rather than misery now and ultimately hell). And 1 Corinthians 13:13 says “these three remain”.
Third, Jesus said “The truth will set you free” (JN 8:32), and “If the Son sets you free, you will be free indeed.” (JN 8:36) As a disciple of Christ I feel free, and I find every day fraught with significance as I fight on God’s side against evil in a war that has ultimate consequences for the destiny of my soul. Spiritual freedom is in Christ.
If Christians retain the same freedom they had as non-Christians to accept or reject Christ’s Lordship, then the second most important truth to learn in life after the Gospel/kerygma is the “necessity” of persevering in accepting Christ as Lord and in learning God’s Word (LGW) until we die in order to achieve our God-given purpose in life: the fullness of Christ or spiritual maturity. [LGW signifies this truth.]
The doctrine of perseverance or LGW serves as a bridge from the kerygma (creed) to the didache (lifelong spiritual growth) or from spiritual birth to maturity, so it is logical to harmonize various/diverse biblical statements on this issue before proceeding to other didachaic topics.
