Yes, Christians Do Have an Assuranceābut Not an Absolute Assuranceāof Salvation
Many Protestants understand being āsavedā as a one-moment-in-time act of repentance and acceptance of Jesus Christ as oneās āpersonal Lord and saviorā (a phrase that nowhere appears in the Bible, by the way), a life-changing transformation of ālostā sinner who becomes a āsavedā child of God. They believe this to be an irrevocable step that eliminates the penalties of past sins and guarantees, no matter what might happen from that point forward, that nothing can undo or rescind oneās salvation.
āOnce-saved-always-savedā is a slogan many Protestants use to describe their belief in a Christianās absolute assurance of salvation. And though not all Protestants accept the once-saved-always-saved formula, many, such as Southern Baptists and the myriad of ānon-denominationalā denominations, do. Two Bible passages commonly cited in support of this view are:
1 John 5:13: āI write this to you who believe in the name of the Son of God, that you may know that you have eternal life.ā
John 10:27-29: āMy sheep hear my voice and I know them, and they follow me; and I give them eternal life, and they shall never perish, and no one shall 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 Fatherās hand.ā
St. Johnās assurance that āyou have eternal lifeā is a proclamation of every Christianās moralānot absoluteāassurance of salvation. Christ offers us the gift of salvation, and he will not go back on his word.
But you and I are entirely capable of going back on our word by abandoning Christ and, thereby, forfeiting his gift of salvation. St. Paul speaks about this in 2 Timothy 2:11-13:
If we have died with him, we shall also live with him; if we endure, we shall also reign with him; if we deny him, he also will deny us; if we are faithless, he remains faithfulā for he cannot deny himself.
Take care to notice the particular āifā in this passage. So while itās true that we may indeed āhaveā salvation, whether or not we keep our grasp on it is another matter, as St. Paul will demonstrate below.
But first, letās consider St. Johnās other statement: No one can snatch out of Christās hand, those whom the Father has given him. No external power is capable of wresting us out of Christās loving embrace (Rom. 8:28-29), but you can do it, if you decide to willfully rebel against God through mortal sin (1 John 5: 16-17), and if you die unrepentant in that state, you will have lost your salvation because you will have, in effect, snatched yourself out of Christās hand. This is demonstrated by the following verses:
Romans 11:13-22: that first of all, contains a description of (and warning to not be like) those individual Jews living at the time of Christ who forfeited their salvation by deliberately rejecting Jesus Christ as Messiah, Redeemer, and Savior. They were once ābranchesā on a cultivated olive tree (i.e., the Chosen People of Israel) that symbolizes in this analogy those who were saved. Pointing toward their sin of spurning their Savior, St Paul declares:
They [i.e., those who lost their salvation by rejecting Christ] were broken off because of their unbelief, but you stand fast only through faith. So do not become proud, but stand in awe. For if God did not spare the natural branches, neither will he spare you. Note then the kindness and the severity of God: severity toward those who have fallen, but Godās kindness to you, provided you continue in his kindness; otherwise you too will be cut off.
The āyouā to whom heās addressing this warning are gentile Christians whom he likens to branches from a āwild olive treeā that had been grafted onto the cultivated tree in places where the natural branches had been snapped off. Note well the warning he gives these gentile Christians regarding the possibility that they too could lose their salvation.
Hebrews 10:26ā31: [I]f we sin deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, but a fearful prospect of judgment, and a fury of fire which will consume the adversaries. . . . How much worse punishment do you think will be deserved by the man who has spurned the Son of God, and profaned the blood of the covenant by which he was sanctified, and outraged the Spirit of grace? For we know him who said, āVengeance is mine, I will repay.ā And again, āThe Lord will judge his people.ā It is a fearful thing to fall into the hands of the living God.
2 Peter 2: 20-21: For if, after they have escaped the defilements of the world through the knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and overpowered, the last state has become worse for them than the first. For it would have been better for them never to have known the way of righteousness than after knowing it to turn back from the holy commandment delivered to them.ā
Ask yourself: Is there any way someone could āescape the defilements of the worldā other than by Godās grace and forgiveness (what many refer to as being āsavedā)? No. So this means that some who been saved fall back into grievous sin, thereby losing their salvation.
And recall the unforgiving servant in Matthew 18:21-35. Heās a perfect parallel with the sinner who repents, pleads for mercy, and was forgiven by God and his debt of sin wiped out. But the unforgiving servant proceeded to mistreat a fellow servant and when the King discovered this, he reinstated his debt and threw him into prison.
The Bible is clear that, tragically, Christians can indeed lose their salvation by sinful rebellion against God. As the Lord himself declared, āSo also my heavenly Father will do to every one of you, if you do not forgive your brother from your heartā (Matt. 18:35).
Ask yourself: Why would Christ warn us about this, if there was no danger that it could happen? See these additional verses for more study: Matt. 7:21-23; Matt. 10:22; John 5:29; Rom. 2:5-11; Rom. 8;24-25; 1 Cor. 9:27; 1 Cor. 10:12; Heb. 6:11; Phil. 2:12-13; 1 John 3:21-24; 1 John 4:20-21.
