The only way that you become acceptable to God is to believe that your sins are forgiven through Jesus Christ. Once you believe this, good works and Christian living will follow, as surely as heat follows fire. But your salvation in no way depends on the amount of good works that you accomplish or sins that you commit here on earth.
But the doctrine of "once saved, always saved" is also false. How can you lose your salvation? No amount of sin or lack of good works will cause you to lose your salvation. The only way that you will lose your salvation is if you stop believing that your sins are forgiven through JC.
That Lutheran teaching guide you've come up with is a practice in the teachings of the Devil.
You're basically say that if we are to continue in sin so that grace might increase. It doesn't work that way.
Romans 6:1-6 (NKJV)
1 What shall we say then? Shall we continue in sin that grace may abound?
2 Certainly not! How shall we who died to sin live any longer in it?
3 Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death?
4 Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.
5 For if we have been united together in the likeness of His death, certainly we also shall be in the likeness of His resurrection,
6 knowing this, that our old man was crucified with Him, that the body of sin might be done away with, that we should no longer be slaves of sin.
You LIVE in sin. You don't hate masturbating to this woman. You just have as you said an "Oh well," attitude. You want to do and do it. I already quoted you a Scripture that those who practice sin are of the Devil and are not saved. You PRACTICE it. I do not. What is the difference? You willfuly and continuously do it. I do not. I find my self in the position of Paul.
Romans 7:14-17 (NIV)
14 We know that the law is spiritual; but I am unspiritual, sold as a slave to sin.
15 I do not understand what I do. For what I want to do I do not do, but what I hate I do.
16 And if I do what I do not want to do, I agree that the law is good.
17 As it is, it is no longer I myself who do it, but it is sin living in me.
You said, "The only way that you will lose your salvation is if you stop believing that your sins are forgiven through JC." This is wrong. Just keep on murdering and if you believe you're sins are forgiven they are? That is about as insidious as it gets. There are plenty of verses that say you can lose salvation for other things.
Jas 2:14-20
14 What use is it, my brethren, if a man says he has faith, but he has no works? Can that faith save him?
15 If a brother or sister is without clothing and in need of daily food,
16 and one of you says to them, ÒGo in peace, be warmed and be filled,Ó and yet you do not give them what is necessary for their body, what use is that?
Jas 5:19-20
19 My brethren, if any among you strays from the truth, and one turns him back,
20 let him know that he who turns a sinner from the error of his way
will save his soul from death, and will cover a multitude of sins.
2 Pe 3:15-16 -
15 and regard the patience of our Lord to be salvation; just as also our beloved brother Paul, according to the wisdom given him, wrote to you,
16 as also in all his letters, speaking in them of these things, in which are some things hard to understand, which the untaught and unstable distort, as they do also the rest of the Scriptures, to their own destruction.
1 Ti 5:8 -
8 But if anyone does not provide for his own, and especially for those of his household, he has denied the faith, and is worse than an unbeliever.
1 Co 9:25-27 -
25 And everyone who competes in the games exercises self-control in all things. They then do it to receive a perishable wreath, but we an imperishable.
26 Therefore I run in such a way, as not without aim; I box in such a way, as not beating the air;
27 but I buffet my body and make it my slave, lest possibly, after I have preached to others, I myself should be disqualified.
And this is what you do not have, or choose not to have because you think grace will cover sins like you do. You do not exercise self control because you live under the mistaken idea that your are forgiven. That is the true danger and that is why you are a hypocrite.
You are a slave of the one you obey. And we can see who you obey.
Romans 6:15-16
15 What then? Shall we sin because we are not under law but under grace? By no means!
16 DonÕt you know that when you offer yourselves to someone to obey him as slaves, you are slaves to the one whom you obeyÑwhether you are slaves to sin, which leads to death, or to obedience, which leads to righteousness?
Lastly, NPRLover is correct that you're actions cause much more damage to the Christian church than anything Satan could dream up. What you're doing is more damaging than any sins that I commit in real life or on an internet bb. Unfortunately, you'll never realize this. If you really want to win converts to Christianity, you should focus on a positive message:
You are as wrong as it gets. Your true nasty hypocrisy is what turns most people off. And your true nasty hypocrisy is why churches are filled with far more sin than they should be. They become walking testimonies to impotent Christianity. What a shame it is.
