I know I am saved based on I Jn. 5:13
Places where Scripture speaks of our ability to know that we are abiding in grace are important and must be taken seriously. But they do not promise that we will be protected from self-deception on this matter. The New Testament teaches us that genuine assurance is possible and desirable, but it also warns us that we can be deceived through a false assurance. Jesus declared: "Not everyone who says to me, 'Lord, Lord' shall enter the kingdom of heaven" (Matt. 7:21).
One can be confident of ones present salvation. This is one of the chief reasons why God gave us the sacramentsto provide visible assurances that he is invisibly providing us with his grace. And one can be confident that one has not thrown away that grace by simply examining ones life and seeing whether one has committed mortal sin. Indeed, the tests that John sets forth in his first epistle to help us know whether we are abiding in grace are, in essence, tests of whether we are dwelling in grave sin. For example, "By this it may be seen who are the children of God, and who are the children of the devil: whoever does not do right is not of God, nor he who does not love his brother" (1 John 3:10), "If any one says, I love God, and hates his brother, he is a liar; for he who does not love his brother whom he has seen, cannot love God whom he has not seen" (1 John 4:20), "For this is the love of God, that we keep his commandments. And his commandments are not burdensome" (1 John 5:3).
Likewise, by looking at the course of ones life in grace and the resolution of ones heart to keep following God, one can also have an assurance of future salvation. It is this Paul speaks of when he writes to the Philippians and says, "And I am sure that he who began a good work in you will bring it to completion at the day of Jesus Christ" (Phil. 1:6). This is not a promise for all Christians, or even necessarily all in the church at Philippi, but it is a confidence that the Philippian Christians in general would make it. The basis of this is their spiritual performance to date, and Paul feels a need to explain to them that there is a basis for his confidence in them. Thus he says, immediately, "It is right for me to feel thus about you all, because I hold you in my heart, for you are all partakers with me of grace, both in my imprisonment and in the defense and confirmation of the gospel" (1:7). The fact that the Philippians performed spiritually by assisting Paul in his imprisonment and ministry showed that their hearts were with God and that it could be expected that they, at least in general, would persevere and remain with God.
There are many saintly men and women who have long lived the Christian life and whose characters are marked with profound spiritual joy and peace. Such individuals can look forward with confidence to their reception in heaven.
Such an individual was Paul, writing at the end of his life, "I have fought the good fight, I have finished the race, I have kept the faith. Henceforth there is laid up for me the crown of righteousness, which the Lord, the righteous judge, will award to me on that Day" (2 Tim. 4:7-8). But earlier in life, even Paul did not claim an infallible assurance, either of his present justification or of his remaining in grace in the future. Concerning his present state, he wrote, "I am not aware of anything against myself, but I am not thereby justified [Gk.,
dedikaiomai]. It is the Lord who judges me" (1 Cor. 4:4). Concerning his remaining life, Paul was frank in admitting that even he could fall away: "I pummel my body and subdue it, lest after preaching to others I myself should be disqualified" (1 Cor. 9:27). Of course, for a spiritual giant such as Paul, it would be quite unexpected and out of character for him to fall from Gods grace. Nevertheless, he points out that, however much confidence in his own salvation he may be warranted in feeling, even he cannot be
infallibly sure either of his own present state or of his future course.
The same is true of us. We can, if our lives display a pattern of perseverance and spiritual fruit, have not only a confidence in our present state of grace but also of our future perseverance with God. Yet we cannot have an infallible certitude of our own salvation, as many Protestants will admit. There is the possibility of self-deception (cf. Matt. 7:22-23). As Jeremiah expressed it, "The heart is deceitful above all things, and desperately corrupt; who can understand it?" (Jer. 17:9). There is also the possibility of falling from grace through mortal sin, and even of falling away from the faith entirely, for as Jesus told us, there are those who "believe for a while and in time of temptation fall away" (Luke 8:13). It is in the light of these warnings and admonitions that we must understand Scriptures positive statements concerning our ability to know and have confidence in our salvation. Assurance we may have; infallible certitude we may not.
For example, Philippians 2:12 says, "Therefore, my beloved, as you have always obeyed, so now, not only as in my presence but much more in my absence,
work out your own salvation with fear and trembling." This is not the language of self-confident assurance. Our salvation is something that remains to be worked out.
In Christ,
