Your theory of atonement failed to realize the universal scope of Christ's sacrifice. God so loved the Kosmos, everyone in it including the dead, they all have the opportunity to believe:
14 "And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up,
15 "that whoever believes in Him should not perish but have eternal life.
16 "For God so loved the world (kosmos) that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
17 "For God did not send His Son into the world (kosmos) to condemn the world(kosmos), but that the world(kosmos) through Him might be saved. (Jn. 3:14-17 NKJ)
Kosmos is repeated four times for emphasis, like four points of the compass denotes the entire globe. Your theory of "limited atonement" left a big part of the
Kosmos out, the realm of human dead. Billions are there, yet you insist the propitation of Christ does not cover the entire
Kosmos:
And He Himself is the propitiation for our sins, and not for ours only but also for the whole world (Kosmos). (1 Jn. 2:2 NKJ)
So your theory is just modified Calvinism. Although you expand atonement beyond a select few, you still select a portion of humanity, and leave out the rest. The very scriptures you cite against Calvinism's limited atonement, can be cited against your theory. The irony of that shouldn't escape anyone.
