Hebrews 2:1-3: Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip. For if the word spoken by angels was stedfast, and every transgression and disobedience received a just recompence of reward; How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard him;...

GOD WILL NOT TOLERATE DISOBEDIENCE
The one major strategy Satan uses, upon which all his other strategies are based, is to weaken, divert and gain control over man's will through DISOBEDIENCE.
Since man's first encounter with Satan in the garden of Eden until now, Satan has been lying, deceiving, tempting and using every possible tactic to cause man to use his will to disobey God.
The church today is filled with Christians who are living defeated lives, unable to take possession of their inheritance as joint-heirs of the Kingdom of God because they are walking in disobedience to God and His Word. Christians cannot be partially obedient to God and His Word, and partially obedient to their own self-wills. It is all or nothing!<< (vacilating somewhere in the middle of all or nothing is termed being lukewarm!)...God said that He would spit us out if we were found to be lukewarm!
Satan, the Arch Deceiver, would like you to believe that because you are living under grace that you can live as you like...following after your own desires, instead of seeking after and following God's will...and still be saved and enjoy the blessings of God. He would like you to think that God does not require the same type of obedience under the New Covenant as He did under the Old Covenant. Satan is a liar!
ALL acts of disobedience are sin, regardless of how small or large an act of disobedience it may be.
Satan's strategy is to destroy yourrelationship with God, by leading you one step at a time into disobedience. If you allow even one area of your life where you walk in disobedience to God's Word to remain, or if you fail to obey God's leading or direction and do not repent, Satan has a stronghold he will use to lead you further into disobedience.
It is not enough to simply hear and agree with what God reveals to us. It is not enough to profess we know God and that we belong to Him. We must obey. We must walk as Jesus walked. Obedience is the proof...the evidence that we truly know God (Romans 2:13; 1 John 2:3-6).
2 Thessalonians 1:7-9 And to you who are troubled rest with us, when the Lord Jesus shall be revealed from heaven with his mighty angels, In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ: Who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of His power;...
THE PENALTY FOR DISOBEDIENCE IS DEATH
Satan's strategy is to deceive and lead Christians into disobedience by lying to them about the consequences of disobedience, making them think they will not be punished for their disobedience.
God made it perfectly clear to Adam that the penalty for disobedience is death (Genesis 2:16-17), yet Satan deceived Eve into believing that she and Adam would not die for their act of disobedience, but would be wise as gods, knowing good and evil (Genesis 3:4-5).
Adam was not deceived (1Timothy 2:14); he knew the penalty, yet he listened to Eve instead of listening to the voice of God...and he willfully chose to disobey God. He yielded his will and took of the fruit and ate it. As a result of Adam and Eve's act of DISOBEDIENCE, they reaped the penalty andlived under the curse of disobedience:
Sin and death entered the world (Romans 5:12).
All men became slaves to sin under Satan's dominion (Romans 6:16-17).
The ground was cursed (Genesis 3:17-19). 
The beautiful, intimate fellowship they had enjoyed with God in the garden of Eden was broken (Genesis 3:24).
There was enmity between God and man (Ephesians 2).
