Paul said that we are not saved by works. He was constantly urging his fellow believers to good works in Christ. To have read his letters is to know that. Surely you have done so.Matthew 19:17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.JESUS also said the following ...John 3:16 For God so loved the world that He gave His only begotten Son, ... that whosoever believeth in Him shall not perish, but will have everlasting life.So, there you have it. You can either attempt to keep the commandments (*perfectly) ... or ... you can believe in JESUS.
17 For God sent not His Son into the world to condemn the world, but that the world, through Him, might be saved.
18 He that believeth in Him is not condemned, but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
Which do you think that you can do ?
* James also said that, even if you only break one commandment, you are guilty of breaking the whole Law. (James 2:10)
Oddly enough, John also says, just a few verses later:
John 3:36 :: New Living Translation
36And all who believe in God's Son have eternal life. Those who don't obey the Son will never experience eternal life, but the wrath of God remains upon them."
John 3:36 :: New American Standard Bible (NASB)
36 "He who (1) believes in the Son has eternal life; but he who (2) does not obey the Son will not see life, but the wrath of God abides on him."
John 3:36 :: English Standard Version (ESV)
36Whoever believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him.
The Kind James Version doesn't use the word OBEY. but, there are versions that do.
As for breakin one, means breaking all, there is thing out there.... it's called repentence. And quite often it is paired with 'and sin no more'. The thing is, that we should be trying.
