Perseverance is the key virtue in the Christian Life because without it, one has no guarantee of a future inheritance with God in heaven. The Scriptures give us guarantees like, “He who began a good work in you will carry it on to completion until the day of Christ Jesus” (Php 1:6) and at the same time they give us strong exhortations like, “continue to work out your salvation with fear and trembling, for it is God who works in you to will and to act according to his good purpose” (Php. 2:12-13). In the Parable of the Sower, Jesus teaches us that only one of the categories of hearers bears fruit and perseveres. All the others are eventually swallowed up and destroyed by malignant influences which militate against Christian perseverance. There are also many warnings in the New Testament about falling away (Cf. Hebrews 6:1-12, etc.). Does a person have a carte blanche (blank check) once he professes faith in Christ? Can he do anything he wants while maintaining blessed assurance in a secure salvation? In his book, The Christian Life, Sinclair Ferguson puts this in perspective,
“Perseverance and faith, therefore, or perseverance and the Christian’s duty to battle on in the fight of faith are never separated and polarized in the Bible. It is never a case of ‘either/or’ always one of ‘both/and.’ In fact we persevere through faith and never apart from it. The picture is one of a dynamic, living trust in a God who actively holds on to us so that we may persevere. There is no blanket guarantee of perseverance. There is no mere doctrine of ‘the security’ of the believer, as though God’s keeping of us took place irrespective of the lives we live. Indeed there is not such thing in the New Testament as a believer whose perseverance is so guaranteed that he can afford to ignore the warning notes which are sounded so frequently.”
While we remain in the fight of faith to persevere the Christian can take great comfort and courage from his Good Shepherd who says, “My sheep hear my voice, and I know them, and they follow me. I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father’s hand. I and the Father are one.” (John 10:27-30)
It is interesting that first century Christians were consumed with two things: (1) A man, Jesus Christ who claimed to be God and (2) An event when this same man was resurrected from the dead. But did Jesus exist? It is a fact that Jesus Christ is the most documented historical character before the age of printing. “No serious scholar has ventured to postulate the non-historicity of Jesus.” (Otto Betz – What Do We Know about Jesus? SCM Press, 1968.) Historically we know that He did exist. The bigger question is the historicity of the resurrection.
When people today think about Christianity, they speak of it as an ideological entity with a political agenda. Others might hold that Christianity is a body of teachings from the greatest Teacher ever, Jesus who taught us an original moral code. But this was not how Christianity was defined in the first century A.D.. Early Christians were known more for their testimony to the historical event of the resurrection of Jesus Christ.
“At no point within the New Testament is there any evidence that the Christians stood for any original philosophy of life or an original ethic. Their sole function is to bear witness to what they claim as an event– the raising of Jesus from among the dead… the one really distinctive thing which the Christians stood was their declaration that Jesus had been raised from the dead…” (J.N.D. Anderson, citing Cambridge professor C.F.D. Moule)
