A Christian (One who has been saved from sin) Can Lose Their Salvation and Become Unsaved

Actually “Lightning”, you’re going backwards now. “Christian” is defined in my initial proposition; “believed and obeyed the gospel of Jesus Christ and been saved from sin”. Scripturally, a Christian is by definition one who has… 1.) Believed the TRUTH of the Gospel of Christ they heard Eph. 1:13 2.) Turned from their past sins 1 Cor. 6:11 3.) Acknowledged and obeyed the TRUTH which they’ve heard and believed Rom. 6:17-18, by being baptized for the forgiveness of sin Acts 2:37-38, 41. “And Crispus, the chief ruler of the synagogue, believed on the Lord with all his house; and many of the Corinthians hearing believed, and were baptized.” Acts 18:8 I truly do not know WHERE you’re getting your “trusted in Jesus Christ as the only Savior” business. Where is that taught in the Bible? Again, my opponent is arguing the surety and steadfastness of the promises of God; an argument I am neither calling into question, nor denying. However, the question on the floor, in this discussion is the faithfulness and steadfastness of the Christian. No, God never revokes His promises. They are indeed firm and fixed. However, Christians can become unfaithful, forsake God, abandon the church, neglect his/her eternal reward and become unsaved? If the answer to this question is “No”, then why is the New Testament utterly replete with warning against transgressing, becoming unfaithful and “falling away” from God. If I need only ONE verse of scripture to complete annihilate my opponent’s position, that verse would be “Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition” 2 Thess. 2:3. The inspired apostles affirmed that God’s wrath will be unleashed upon His enemies (the persecutors of Christians) AFTER a mass “falling away” of unfaithful Christians. The prophet Jude had this to say to warn first century Christians from falling from God’s grace and losing their salvation and Heavenly reward (PLEASE READ THIS CAREFULLY): “I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not.” Jude 5 Yes, God had once “saved” them, having promised them “rest” in the land of Canaan, hence “the land of promise”. But, those same “saved” souls were later destroyed, having become unfaithful and disobedient. Paul explicitly outlined this change of event, in detail: “Moreover, brethren, I would not that ye should be ignorant, how that all our fathers were under the cloud, and all passed through the sea; and were all baptized unto Moses in the cloud and in the sea; and did all eat the same spiritual meat; and did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ. But with many of them God was not well pleased: for they were overthrown in the wilderness. Now these things were our examples, to the intent we should not lust after evil things, as they also lusted. Neither be ye idolaters, as were some of them; as it is written, the people sat down to eat and drink, and rose up to play. Neither let us commit fornication, as some of them committed, and fell in one day three and twenty thousand. Neither let us tempt Christ as some of them also tempted and were destroyed of serpents. Neither murmur ye, as some of them also murmured, and were destroyed of the destroyer. Now all these things happened unto them for ensamples: and they are written for our admonition, upon whom the ends of the world are come. Wherefore let him that thinketh he standeth take heed lest he fall.” 1 Cor. 10:1-12 Now, answer this “Lightning”. Why did the inspired apostles call these “our EXAMAPLES and WARNING” if it were NOT POSSIBLE for Christians to likewise become, unfaithful and unbelieving and ultimately “fall away” and fall short of our reward? Finally, the inspired writer of Hebrews made it totally CLEAR that the once “saved” Christian can develop “an evil heart of unbelief, in departing from the living God” Heb. 3:12. Now, can you “DE-part” (be “removed”) or “separate” from anything of which you were never part OF or connected TO? IMPOSSIBLE! Nevertheless, the writer warns that the Christian's unfaithfulness leads to and results in “removal” and “separation” FROM the living God who at one time saved him/her.
