Doesn't address eternal salvation - it tells you to act Godly.
Ephesians 4:30And do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption.
A wax seal was put on to indicate that the document was genuine. It is not a baggie, nor is it a guarantee that the person who receives it doesn't tear it up - which is what sin does.
1 John 5:13 I write these things to you who believe in the name of the Son of God so that you may know that you have eternal life.
Check out what 'may know' really means.
It's not presumptuous to believe that if we're saved we stay saved buy God's grace and not through our own efforts. It's simply trusting God to do what He said He'd do.
You can believe in anything you want. I give you Scriptural proofs of what God has instructed us and what the Faith consists of. If you don't like it, then Martin Luther's any milkmaid model applies, doesn't it?

And, you must like milk, too, right?
The wages of sin is death. You have to keep the Law perfectly and no one can.
James 2:10 For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it.
If that's what you want to be judged by, you certainly will be, but you won't be very happy with the result.
Romans 8:2-4 For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death. For God has done what the law, weakened by the flesh, could not do. By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh, in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit.
The believer who trusts in Christ IS forgiven and HAS eternal life. Anyone who thinks that they can, or have to, add anything to the work of Christ on the cross is essentially spitting in His face, telling Him that what He did wasn't good enough but the measly, pitiful, imperfect works that they do is. What an insult to Christ.
Imagine that. Christ's painful agonizing death on the cross to pay for sins doesn't earn man a place in heaven without that man adding some pitiful, painless, attempts at what he labels good works, like .....(fill in the blank). Any good work which you think completes what Jesus did because what he did wasn't enough.
Note what Peter did NOT say: "Believe in Jesus, get baptized, come to my church, participate in the communion sacrament, be good, don't sin - and if you do, go to confession and do penance, and maybe, if you are faithful enough, you will first go through torture in a place called Purgatory for some time, and then you will be saved and be in Heaven." Now THAT might be what an uninformed "milkmaid" might have told him if he had been around when Luther was first starting out.
