I must start by stating that both Eternal Security and Conditional Security are not essential doctrines to Christianity unless taken to extremes. By keeping either doctrines within their classical context they cannot cause a person to stumble; thus teaching either one is not worthy of a millstone. However, when either of these doctrines are taken to extreme they both become dangerous.
Is it possible to stop believing, I really do not know. We are looking into whether or not one may lose his salvation; however, during my research I came to the conclusion that the real question is stated in my title. It would seem to me that one can in fact become apostate, but the likelihood of this seems impossible. There is enough Scriptural support to state that saved individuals can in fact reject or commit spiritual suicide (Hebrews 10:22-31 and John 10:28). I believe that nothing external can separate us from God, only our own unbelief. For a believer to walk away from the grace of God is what blasphemy of the Holy Spirit is, and this is unpardonable. As stated in Hebrews 6:4-6 (For in the case of those who have once been enlightened and have tasted of the heavenly gift and have been made partakers of the Holy Spirit, (5) and have tasted the good word of God and the powers of the age to come, (6) and then have fallen away, it is impossible to renew them again to repentance, since they again crucify to themselves the Son of God and put Him to open shame.) a person who has “fallen away” cannot be restored.
Now, conditional security may be true but is it possible? My struggle here is that when we become a new creation, and with this we are given a new nature. Our new nature has new desires for godliness; I do not see how it is possible that the free will that we do have would violate our godly nature to the degree of apostasy. What a dilemma I find myself in, maybe this is where I will leave it rest?
People may say, “What about this person and that person who was faithful but now fallen?” I believe that the majority of these cases are not a part of the security debate but are cases of false conversion. Goats walking among the true herd as it is stated in 1 John 2:19 “They went out from us, but they were not really of us; for if they had been of us, they would have remained with us; but they went out, so that it would be shown that they all are not of us.” For us, it is not possible to know if a person’s conversion was in fact authentic, I suppose time will tell.
We do know that God is judge and that His wisdom is beyond our understanding, knowing all- He truly is just and righteous. Whether you subscribe to conditional or unconditional security know that it is God who judges and that you can have security by believing and doing God’s will. It may be another discussion but I feel it is important to incorporate Matthew 7:21 and James 2:17 into my conclusion. If we do not have the desire to the will of God, we are not saved, we have not been reborn.
May peace, love, and every sort of spiritual blessings be poured out upon all of your lives!
