What was the first sin after creation? If you think it was Adam and Eve eating of the forbidden fruit, you need to look back a little further. When Adam sinned, there had already been an open rebellion against God by the “anointed cherub” called Lucifer, or Light Bearer. He was a created angel of the highest order. Isaiah describes his sinful pride and fall: “How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations! For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north: I will ascend above the heights of the clouds; I will be like the most High. Yet thou shalt be brought down to hell, to the sides of the pit. (Isaiah 14:12-15)” But before he is cast into eternal Hell, the Bible tells us that he and his cohorts (demons) are determined to be the enemies of our souls. How so?…
First, he keeps people from coming to Christ for forgiveness by blinding their minds. “In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them. (2Corinthians 4:4)”
Secondly, he tells lies, “Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it. (John 8:44)”
Thirdly, he disguises himself as someone who is good. “And no marvel; for Satan himself is transformed into an angel of light. (2Corinthians 11:14)”
There are other evil tactics, but you get the point. So what should we do? Is there a way to protect ourselves from the evil one? Yes, but first you must know Jesus Christ as your personal Lord and Savior, and then, “…be strong in the Lord, and in the power of his might. Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. (Ephesians 6:10-12)” and “Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour: (1Peter 5:8)”
