That is not enough. You must believe on the Lord Jesus Christ and trust in his finished work alone.
By grace are ye saved through faith and that no of yourselves: it is a gift of God: Not of works, lest any man should boast. (Ephesians 2:8,9)
New or old testament, saints are saved in the same way of faith:
For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness. Now him that worketh is the reward not reckoned of grace, but of debt. But to him that worketh not, but believeth on him that jusifieth the ungodly, his faith is counted for righteousness. Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works, Saying, Blessed are they whose iniquities are forgiven, and whose sins are covered. Blessed is the man to whom the Lord will not impute sin. (Romans 4:3-8)
You would have me condemned to death and stoned.
Many Christians mistakenly believe they are no longer subject to the law. Jesus did not destroy the law and the prophets. He came to fulfil them.
Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.For verily, I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. Whosoever therefore shall break one of these least commandements, and shall teach men so, he shall be called least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven. (Matthew 5:17-19)
If you commit murder, and I were to sit on your jury and the evidence was beyond a reasonable doubt, I would have to judge you guilty. During the penalty phase of the trial, you may receive a sentence of death.
If you are a believer, then your soul, with its quickened spirit, will never die. (See John 5:24 and John 11:25) All of our sins are forgiven by him, but we may have to suffer the consequences of them in this life. The laws of the nation within which you live may not conform to God's law (sexual sin) but God finds them abhorent even now. If you do not like this, your problem is with God, not me.
And God's law is still in effect with the exception of those ordinances pertaining to "gifts and sacrifices" and "meats, and drinks, and divers washing, and carnal ordinances" imposed upon the children of Israel "until the time of the reformation" (see Hebrews 9)
I bet you believe Jesus turned water into grape juice?
I am quite familiar with the mocking spirit which prompts such a remark. If you are in fact a christian, you certainly are not behaving like one. I actually read the Bible and believe what it says. (I have tried to encourage to do the same). At the wedding of Cana in John chapter 2, Jesus made "wine" and very good wine at that, as attested by the governor of the feast.
