If, eternal security is not guaranteed through the shed blood of Jesus on the cross, then what can YOU do to earn your security??
Scripture teaches that one’s final salvation depends on the state of the soul at death. As Jesus himself tells us, "He who endures to the end will be saved" (Matt. 24:13; cf. 25:31–46). One who dies in the state of friendship with God (the state of grace) will go to heaven. The one who dies in a state of enmity and rebellion against God (the state of mortal sin) will go to hell.
Can you be assured of salvation? As the Bible says, you are already saved (Rom. 8:24, Eph. 2:5–8), but you're also being saved (1 Cor. 1:18, 2 Cor. 2:15, Phil. 2:12), and you have the hope that you will be saved (Rom. 5:9–10, 1 Cor. 3:12–15). Like the apostle Paul you are working out your salvation in fear and trembling (Phil. 2:12), with hopeful confidence in the promises of Christ (Rom. 5:2, 2 Tim. 2:11–13).
