My friend, what I am about to say, I say to your shame. The verse you are wresting to your own destruction (2 Peter 3:15-16), is Ephesians 2:8-9 which says:
"For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: not of works, lest any man should boast."
But you, rwb, have failed to obey the Holy Ghost who said:
"Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth."
For if you had done so, which you clearly have not, then you would have known that the epistle to the Ephesians is not written to people like you who think that they are christians, but have never obeyed the gospel of the Lord Jesus Christ. The epistle is written to:
"...The saints which are at Ephesus, and to the faithful in Christ Jesus..." (Ephesians 1:1).
How did the Ephesians become saints, rwb? They became saints when they were:
"...Baptized in the name of the Lord Jesus. And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied." (Acts 19:5-6).
They were saved by baptism, calling on the name of the Lord (Acts 2:21, Acts 2:38) which is for the remission of sins. And they received the Holy Ghost which will cause men to speak with tongues and magnify God (Mark 16:17, Acts 2:4, Acts 2:39, Acts 10:46).
This is how they were, by the grace of God, saved through faith; and that not of themselves: it is the gift of God: not of works, lest any man should boast. Even their faith through which they obeyed the gospel was not of themselves. Because:
"...Faith cometh by hearing, and hearing by the word of God." (Romans 10:17).
God hath dealt to every man the measure of faith. Therefore, rwb, if you (in your open rebellion against God and his holy word) imagine that us christians have something to "boast" over because we have obeyed the Gospel, then I testify to you in the name of Jesus Christ, (the name through which I received remission of sins), that you are a fool and blind.
It is not of any works of righteousness which we have done that saved us. For by the works of the law shall no flesh be justified:
"...But according to his MERCY he saved us, by the washing of regeneration, AND renewing of the Holy Ghost..." (Titus 3:5).
Therefore, rwb, I set before you life and death. Choose life.
