God created a perfect world and man was perfect until the lies and deceptions of satan caused Adam and Eve to sin by taking from the tree of knowledge.
The world and man are spoiled. Man lusts after things of the flesh (things in and of this world). We lust after things that are spoiled and are only a moment in time. We give up eternal life with The Almighty God. Everything we see is still God's creation, but not perfect like it was.
1 John 2:15-17
Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world. And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.
The lies of satan spread. When Jesus walked the earth he warned His disciples about it in Matthew 16:5-12
And when his disciples were come to the other side, they had forgotten to take bread. Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees. And they reasoned among themselves, saying, It is because we have taken no bread. Which when Jesus perceived, he said unto them, O ye of little faith, why reason ye among yourselves, because ye have brought no bread? Do ye not yet understand, neither remember the five loaves of the five thousand, and how many baskets ye took up? Neither the seven loaves of the four thousand, and how many baskets ye took up? How is it that ye do not understand that I spake it not to you concerning bread, that ye should beware of the leaven of the Pharisees and of the Sadducees? Then understood they how that he bade them not beware of the leaven of bread, but of the doctrine of the Pharisees and of the Sadducees.
Their doctrine: They don't believe in the resurrection of Jesus and the Holy Ghost. The pharisees say they believe, but said Jesus couldn't cast out devils, except by the power of satin, not the Holy Ghost.
Matthew 12:24
But when the Pharisees heard it, they said, This fellow doth not cast out devils, but by Beelzebub the prince of the devils.
Acts 23:8
For the Sadducees say that there is no resurrection, neither angel, nor spirit: but the Pharisees confess both.
Even some of the people that followed the disciples for awhile were of satan:
1 John 2:18-19
Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time. They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us.
By the early centuries after the death and resurrection of Jesus Christ the doctrine of antichrist was well established in the world. Instead of obeying God's commandments, man made his own laws. It's been going on for so long, satan is gathering in more everyday because alot of people are blinded by his deceptions, but alot of people still do hear Jesus call and aren't blinded by satan and led away. I pray you are one that hears Him.
2 Timothy 3:1-9
This know also, that in the last days perilous times shall come. For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good, Traitors, heady, highminded, lovers of pleasures more than lovers of God; Having a form of godliness, but denying the power thereof: from such turn away. For of this sort are they which creep into houses, and lead captive silly women laden with sins, led away with divers lusts, Ever learning, and never able to come to the knowledge of the truth. Now as Jannes and Jambres withstood Moses, so do these also resist the truth: men of corrupt minds, reprobate concerning the faith. But they shall proceed no further: for their folly shall be manifest unto all men, as theirs also was.
