God had a reason for Christ to die;
True. After man sinned, God and the Word planned, that He become the Lamb slain for sins of man.
Gen 3:15And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
The only preplanning of God and the Lamb after man sinned, was before He came in the flesh.
Christ's death was not an end in itself.
True. Dying for sins at the hands of sinful man, was only to make any man's sin exceeding sinful to all men.
Resurrecting from the dead is to bring sinners to repentance for His mercy's sake.
Rom 4:24But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead; Who was delivered for our offences, and was raised again for our justification.
Basically, you translated "God caused man to become sinful" to "God created man sinful". Here, you cut God's purposes off at the death of Christ.
God purposing any creature to sin, cuts off and lies against His purpose of creation.
Rev 4:11Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created.
There are at least two uses of the term, God's will (and similar phrases), in Scripture. I thought you already knew that.
1) His will is that we obey him (command).
2) He is not willing that any [of his elect] should perish (plan/decree).
True. Jesus Christ does not intend any man to disobey Him and die.
Hebrews{13:8} Jesus Christ the same yesterday, and to day, and for ever.
Only that old serpent the devil intends man to sin, and always tempts man to do so.
Jas 1:13Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man:
Is God so weak, that he can only tell people what he wants, and wait on THEM to accomplish it?
What you call weakness, Jesus calls meekness:
Mat 11:28Come unto me, all ye that labour and are heavy laden, and I will give you rest.Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.For my yoke is easy, and my burden is light.
Ihat he can only tell people what he wants, and wait on THEM to accomplish it?
Of course, it's called faith in the word of God:
Gen 22:12And he said, Lay not thine hand upon the lad, neither do thou any thing unto him: for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son from me.
What you call predeterminism, is not what God calls faith. Predetermism cuts off and forbids faith.
1Pe 5:8 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour: Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world.
The faith of predeterminst pseudo-Christian pagan fatalism is no faith at all.
Does your God fly by the seat of his pants, putting out fires, and inventing new ways to handle all the mistakes?
It wasn't by the seat of His pants but by His own hands and feet, that He planned to die for us after after Adam sinned.
Gen 3:15And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
He only flies to earth when He comes a second time from heaven.
Rev 19:11 And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war.
You already said that above. It does not read like his primary purpose was to die.
Yes, it was. If His purpose was to die at creation, and making men to sin to kill Him, His primary purpose here is dying. Creation and man became only a necessary tool for His manner of death.
Only one Christ intends and tempts men to sin, for the purpose of killing the Son in the flesh:
Gen 3:1 Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden?
Gen 3:15And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
The death of Christ was an enormous means to an end, which is found in Rev 21 among other places.
True. It's the beginning that God intended on this earth, to dwell with man in the light forever.
But after man sinned and did evil rather than the good God intended on earth, it was necessary for God with the Word to plan on dying for our sins, and resurrect from the dead for our justification. Otherwise, after man sinned, He would need to destroy all men from the earth.
Rev 13:8And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
The Lamb planned to be slain for sins from the foundation of the world, not before, nor at the laying thereof.
Heb 1:20 And, Thou, Lord, in the beginning hast laid the foundation of the earth; and the heavens are the works of thine hands:
Gen 1:31
And God saw every thing that he had made, and, behold,
it was very good. And the evening and the morning were the sixth day.
Gen 2:1 Thus the heavens and the earth were finished, and all the host of them. And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made.
All things were good at the foundation of the world, and God rested without any evil thought nor intent for the world, and all creatures He had made.
1 Tim 6:3 If any man teach otherwise, and consent not to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness; He is proud, knowing nothing, but doting about questions and strifes of words, whereof cometh envy, strife, railings, evil surmisings,
Predeterminists accuse God of being an evil surmiser at creation, thinking evil intent toward His own creatures.
Tit 1:15Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled.
