It is a brutally effective way of showing who the real God is
Brutal? Or Beautiful? The character of God and the word of God, divides people. The above statement is a perfect example.
The beauty and anchor of faith in God is captured in Isaiah 49:15:
Can a woman forget her nursing child, And not have compassion on the son of her womb? Surely they may forget, Yet I will not forget you.
When God walked among us as a man, he told us the same thing: And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand
How could anyone be considered sane that rejects a God that is so utterly devoted to his own ?
The bible answers, "For the creature was made subject to vanity". Being a slave to their own vain viewpoints, much of mankind cannot see the goodness of God. So, God gives some people what they want - freedom from himself.
Just image the level of depravity that is revealed in a person who chooses hell over the tender care from God that is comparable to a nursing mother. Let that sink in a minute.
