First thing you need to understand is why did God allow His only begotten Son to be crucified to save humanity. He let Jesus die to allow us to be reborn and be, redeemed from sin and destruction.
You must understand that the Devil, the evil one does not want you to recognise the sacrifice that Jesus made to save your life and put you in the house of God. The Devil wish to rob your eternal life and doom you to be, destroyed as he will eventually be.
Matthew 10:28 And fear not them which kill the body, but are not able to kill the soul: but rather fear him which can destroy both soul and body in hell. Just imagine that the Devil can influence millions of people to sin against God so that He as to kill hundred and thousand of His children souls. Satan would have achieved one of the things he set out to do that will cause God’s regret.
Joshua 22:5 But take diligent heed to do the commandment and the law, which Moses, the servant of the Lord, charged you. To love the Lord your God, and to walk in all his ways. Keep his commandments cleave unto him, to serve him with all your heart and with all your soul.
Having recognised the instructions from God, Satan decided to put forward many temptations of His own. He was unable to tempt the Son of God; therefore, He turned His attention to humanity.
Satan’s arsenal consists of pride, greed, gluttony, wrath, lust, sloth and envy, known as the seven deadly sins. The Devil knows that there are eternal, unforgivable and unpardonable sins which will not be, forgiven by God.
Satan hopes that you do not know about these instructions; therefore, he can pull the wool over your eyes and get you to curse the living God.
Mark 3:28-29 Verily I say unto you, All sins shall be, forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme. But he that shall blaspheme against the Holy Ghost hath never forgiveness but is in danger of eternal damnation.
Luke 12:10 And whosoever shall speak a word against the Son of man, it shall be, forgiven him: but unto him that blasphemeth against the Holy Ghost it shall not be, overlooked.
