Sinners are saved by grace through faith.

Lutero said:

Sinners are saved by grace through faith.

But not by grace alone nor faith alone. Scripture is very clear:

Romans 2:13
(For not the hearers of the law are just before God, but the doers of the law shall be justified.

And just calling Jesus Lord, won't save you either. Scripture is clear:
Matthew 7:21
Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the willof my Father which is in heaven.

But you claim that you deserve salvation by your faith ALONE. How is it that you judge yourself before time?
1 Corinthians 4:5
Therefore judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts: and then shall every man have praise of God.

It seems it is because you save yourself. Where is God in your equation?You claim that you are saved by your faith alone. Therefore, you must deserve that salvation. Or you must be saving yourself. 

Try to keep up.

You have fallen behind.

Kinda sorta sometimes keeping God's commandments will not save you. 

Scripture says that God forgives. And Scripture also says:
John 14:15
If ye love me, keep my commandments.

Since you deny that you need to keep any Commandments, what does that say about your love for Christ?

LOL.

Keep laughing.

You can always try having faith in the Good News.

My faith is demonstrated in my works. I do my best to keep the Commandments. But you reject them. What does that say about your love for Christ?

How much obedience saves the sinner?

How much disobedience saves the sinner? That is what you should be asking yourself. Since you deny that you need to keep the Commandments, YOU AREN'T EVEN TRYING TO OBEY. Therefore, you have rejected God and His salvation:
Hebrews 5:9
And being made perfect, he became the author of eternal salvation unto all them that obey him;

A little obedience?

Some obedience?

A bunch of obedience?

Or perfect obedience?

Please let us know.

Because you don't realize that you need God, you don't understand that it is God who judges whether we have been OBEDIENT ENOUGH. He is our Judge. You constantly try to replace Him. But you are not my Judge. Whether I have done enough to demonstrate my faith, God knows. Whether you think I'm doing enough is of no concern to me:
1 Corinthians 4:2-4

King James Version (KJV)
²Moreover it is required in stewards, that a man be found faithful.
³But with me it is a very small thing that I should be judged of you, or of man's judgment: yea, I judge not mine own self.
⁴For I know nothing by myself; yet am I not hereby justified: but he that judgeth me is the Lord.

BTW, RCs would save themselves so much trouble if only they would read the Word of God and believe it.

It is the other way around. Protestants would save themselves a great deal of trouble if they would read the Word of God and believe it and then do the will of God as He disclosed in the Scriptures. Simply reading His Word is NOT ENOUGH.
James 1:22
But be ye doers of the word, and not hearers only, deceiving your own selves.

Sincerely,

De Maria
