Imagine, you're an omniscient, omnipotent deity and you've created humans who are going to behave badly and disobey you, but you love them and want to save them from the terrible punishment you've prepared for them for behaving the way you designed them.
Because you're omniscient, you know exactly what will save these creations and you desperately want to save them because you love them. You have always known this because you know all things.
The only thing that will save them is to have yourself manifest in human form and have yourself sacrificed as the ultimate blood sacrifice because everyone knows that blood sacrifices impress and satiate gods. It's the only thing that will work; there is no alternative. And you have always know this would be needed.
You even inspire the authorship of a book and in that book, according to some people, you include lots of hints and 'prophecies' about a 'Messiah' coming as a saviour. You even tell 'Isaiah' although you get the name of the 'Messiah' wrong.
But you still don't do anything even though you know what's needed and you've decided to do it. Instead, you wait about another 1000 years, allowing millions of people that you love above all else, to not be 'saved', and keeping them in complete darkness about the solution.
Then about 2020 years ago, for no apparent reason it should be at that precise moment, you decide to act and impregnate a virgin so you can be born and grow up as a human, then you get yourself 'executed' and pretend to be dead for 3 days.
And that does the trick. You can now 'save' people from yourself.
Some people apparently find this story convincing but they never think to ask why God waited so long. Why didn't God do this right away when it saw Adam and Eve begin to go wrong? Why didn't it do it after Noah and the animals got off the Ark?
And why did it tell humans that they needed to be saved and that it had provided this vital way, in a manner which took the best part of another 1800 years before everyone got to know about it, so allowing even more millions to not be 'saved'?
It's all rather odd. It really doesn't sound as though this god was really that bothered.
Can a Christian explain this apparent tardiness?
