Many who profess God with their lips deny God in their daily living. Some do this in ignorance. Some do this having been taught lies by the deceived and by the deceivers.
Read the Holy Scriptures below through to verse 14.
Romans 6:1-23 KJV
 What shall we say then? Shall we continue in sin, that grace may abound?
 God forbid. How shall we, that are dead to sin, live any longer therein?
 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
 For he that is dead is freed from sin.
 Now if we be dead with Christ, we believe that we shall also live with him:
 Knowing that Christ being raised from the dead dieth no more; death hath no more dominion over him.
 For in that he died, he died unto sin once: but in that he liveth, he liveth unto God.
 Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
 Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.  Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God.
 For sin shall not have dominion over you: for ye are not under the law, but under grace.
Many quote verse 15 without chewing well verses 1-14. Verse 15 is speaking of those who have died to sin. They are no longer under the law, but are under grace. Verse 15 is speaking of those who have become a new creature. They are now alive living in Christ. These are not under the law; for to be under the law is to be living in sin and not living in Christ. To be living under grace means the old man is dead—crucified with Christ. He is a new creature, resurrected with Christ, leaving sin. He has turned away from sin. He is dead to sin and now lives in Christ by grace through faith.
The law of God is just as natural to keep, observe, do as it is to breathe. We delight in God’s law of love: The Ten Commandments. They are not grievous.
In verse 8, death has no more dominion over him. Sin has no dominion over the soul. When one comes to God by faith surrendering, confessing their known sins to God, repenting, they are justified right then. They are baptized going down into the watery grave and resurrected up out of the watery grave representing a new creature in Christ. Then that soul by faith goes on living unto God in Christ righteousness. By faith they go on daily for the remainder of their lives choosing to die daily and be sanctified by God, sanctified by Christ’s Sabbath, and sanctified by the Word of God.
Verse 11 tells us we are to be dead to sin like Christ is dead to sin.
Verse 15 does not apply to those who believe and live in sin—teaching with their lives that they can still be justified, sanctified, and have Christ’s righteousness, while disobeying Christ’s law of love: The Ten Commandments. These are under the law and not under grace.
Now read again verses 1-14 slowly, and continue reading slowly verse 15, then on to the end.
 What then? shall we sin, because we are not under the law, but under grace? God forbid.  Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?  But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you.  Being then made free from sin, ye became the servants of righteousness.
 I speak after the manner of men because of the infirmity of your flesh: for as ye have yielded your members servants to uncleanness and to iniquity unto iniquity; even so now yield your members servants to righteousness unto holiness.
 For when ye were the servants of sin, ye were free from righteousness.
 What fruit had ye then in those things whereof ye are now ashamed? for the end of those things is death.
 But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life.
 For the wages of sin is death; but the gift of God is eternal life through ab Jesus Christ our Lord.
That my friends is the truth, and nothing but the truth. The truth is the truth, whether you accept it or not, whether you live it or not. Period.
