Why would God "TRY" Abraham's faith before he would account him as "righteous" enough to be saved, and then no try our faith before saving us??
I should point out that Abraham did not have a "comforter" (Spirit) as a "helper", Abraham simply "believed" ON HIS OWN.
Heb 11:17 By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son,
18 Of whom it was said, That in Isaac shall thy seed be called:
19 Accounting that God was able to raise him up, even from the dead; from whence also he received him in a figure.
God had not told Abraham he would raise Isaac back up, Abraham figured that out ON HIS OWN and believed it.
There was no Spirit enabling him, he was not accounted as righteous (regenerated) until "AFTER" his faith was demonstrated, and most of all a "CHOICE" was placed in front of him.
Now calvin comes along and says, OH, No, God has a different plan of salvation for you,
God won't try your faith before he'll save you, he'll regenerate you so you'll have the faith to believe and don't worry about having to make a "CHOICE", you don't have one, If you're predestine to Heaven, there's no way you can miss it, and if you're predestine to hell there's no way you can get to heaven, God lied when he said he wasn't willing for any to perish.
As I've said, Calvin doctrine is "Backward", but then so are all "False doctrine".
Isa 5:20 Woe unto them that call evil good, and good evil; that put darkness for light, and light for darkness; that put bitter for sweet, and sweet for bitter!
