I am Armenian in doctrine. One of the misconceptions concerning Armenian beliefs, is that a sin will separate you from Christ just as a sin separated Adam from God in the beginning. How could this not be the case, if we believe that salvation can be and will be lost by some? Consider with me for a moment Sampson. He lived basically a life of debouchery along side a life of God’s blessing. Sampson’s blessing was contained in his obedience to his Nazarite vow. Had he been separated from God by his sin he would have had no strength.
Then consider David. He both murdered and committed adultery but God did not cast him away. David repented when confronted with his sin. He at one point in his life, some say that it was during this time of his life, that he cried out to God: take not Thy Holy Spirit from me. Why did David make that plea? David had been sent to minister to King Saul as a very young man. Saul who had been given a new heart and prophetic spirit, when he was anointed King by Samuel, had lost that anointing and it had been replaced by an evil spirit. David knew well what rejection of God as Lord of his life and circumstance could yield.
So, what than makes the “falling away” taught in Scripture equivalent to the loss of salvation. Salvation is not a position it is a person. The person of God’s Christ taking up residence in you. Jesus said: abide in Me. Another way of saying that would be: remain in Me. Jesus promises to never leave or forsake us. You on the other hand are given the power to become the sons of God.
John 1:12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: (KJV)
This is why Jesus stated; Matthew 10:32 Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven. 33 But whosoever shall deny me before men, him will I also deny before my Father which is in heaven. (KJV)
The apostle Paul understood these things:
This is a faithful and trustworthy saying: If we died with Him, we will also live with Him; If we endure, we will also reign with Him; If we deny Him, He will also deny us; If we are faithless, He remains faithful [true to His word and His righteous character], for He cannot deny Himself. 2 Timothy 2:11-13 AMP
Paul also confirms to Timothy that the proper teaching of this doctrine can equal salvation or the loss thereof.
1 Timothy 4:16 Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee. (KJV)
False prophets don’t always start out that way. Be a Berean. The Holy Spirit in us is Christ’s gift to us to lead us into all truth. Denying Him is like a divorce. Sin can lead to this divorce, but it’s the divorce that causes the loss of salvation, because it involves unbelief, and being cut off.
