The law was not intended to bring death, but life:
10 I found that the very commandment that was intended to bring life actually brought death. (Roman's 7:10).
It was sin that bought death:
11 For sin, seizing the opportunity afforded by the commandment, deceived me, and through the commandment put me to death. 12 So then, the law is holy, and the commandment is holy, righteous and good.(Romans 7:11)
You are not under the law, IF you follow the spirit. Because nothing the spirit leads you to is against the law.
18 But if you are led by the Spirit, you are not under the law. (Galatians 5:18)
22 But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, 23 gentleness and self-control. Against such things there is no law. 2 (Galatians 5:22)
However, it you are living according to the flesh (Whether or not you have accepted Christ) you will certainly die.
19 The acts of the flesh are obvious: sexual immorality, impurity and debauchery; 20 idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions 21 and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.(Galatians 5:19)
A person who believes in Christ is not necessarily IN Christ. Here is John's assessment of those who are IN Christ:
5 But if anyone obeys his word, love for God[a] is truly made complete in them. This is how we know we are in him: 6 Whoever claims to live in him must live as Jesus did. (1 John 2:5)
There is no condemnation for those who are IN Christ:
Therefore, there is now no condemnation for those who are in Christ Jesus,
Romans 8:1-3
Don't be decieved into believing you can go on sinning and be covered by Christ. As the Apostle John said.
6 No one who lives in him keeps on sinning. No one who continues to sin has either seen him or known him.
7 Dear children, do not let anyone lead you astray. The one who does what is right is righteous, just as he is righteous. 8 The one who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work. 9 No one who is born of God will continue to sin, because God’s seed remains in them; they cannot go on sinning, because they have been born of God. 10 This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not God’s child,(1 John 3: 7)
As Christ Said:
26 But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. 27 The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash.”(Matthew 7:26)
