There are fables, popular in mainstream Christianity, and one of them goes something like this: "Once upon a time, God had a perfect plan: He wanted to save everyone, but man's free will continually frustrates this plan."
The Bible teaches that God has a "determinate counsel," which is according to His foreknowledge; and we are but clay in His hands.
The prophet Isaiah said, "Shall the work say of him that made it, "He made me not!"?" In modern Christianity they teach that it is we who determine what we will be by the choices we make. But the truth is that the choices we make are already predetermined by what we were made to be by God. Our choices only reveal to us what God has already made us to be.
In the world we live in today, the true God, the God of the Bible, if ever heard of, in truth, is not appealing to most people:
"I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things." Isaiah Chapter 45
"I kill and I make alive, I wound and I heal," Deuteronomy Chapter 32
People who sit in churches cannot endure sound doctrine, but after their own lust; have heaped to themselves teachers who are willing to pervert the doctrine of the Apostles and Prophets so as to please them.
In this manner, men have fashioned god in their own image and after their likeness. They have turned their ears away from the truth unto fables. They still identify this strange God as being the Bible-God: Jesus Christ. But all that they do and teach in the name of Jesus Christ is perverted and reprobate concerning the faith.
In philosophy they talk about the "problem of evil," in seminaries and on the net they talk about this, "problem of evil," but evil is not a problem for God; God created evil for a purpose, evil is God's tool.
People acknowledge that God created everything, but are slow to acknowledge that God created evil. Not just more passive evils like earthquakes, disease, and floods; but the evils men want to claim they have created: wickedness in their hearts; and shall we speak of the evil angels? Yes, God made them that way too.
Not that God took otherwise "good" souls and implanted evil in them; but God created souls that were, by nature, wicked and evil in His sight. If He did not make them as they are, then they would not exist as their own conscious selves.
Why? Foremost, it suits His purpose, the world exists to please God, and God is pleased that those He has chosen to become His sons be conformed to the image of His only begotten Son, Christ Jesus. And according to His purpose He made evil in this time, it serves Him and them.
Now people are objecting: "I can't serve a God like that, God is not fair." But God is fair, that which is made for destruction, goes to destruction; and that which is ordained to life, to life. Those who say they cannot serve Him are right: they cannot.
God does not owe man a living, and if man lives at all, it is by the goodness of God, because there are countless people who will never be born, who do not have life, and do not share in that goodness as do all the living sons of men.
God, by his mercy, gives to some, those whom he chooses, life eternal. And even if that which dies suffers, or is in torment, or pain; that does not make God bad. Those who hate God will always see Him as evil, that is even the way they were created to see Him, He brings evil upon them.
What an awesome, great, and terrible God.
