Jesus blood and death paid our debt. It was the greatest sacrifice in the history of the universe. I do not doubt the power of Jesus. He is the Savior. He saved us all. Yet, we are all not saved. The Bible teaches that once you are saved through the power of Jesus, you are forever saved. If not, then you weren't saved to begin with.
There are many things most cannot understand without being taught by the teachers who have Jesus.
Acts 3:19--Repentence gets sin blotted out. If Jesus paid everyones sin they wouldn't have to die, yet all do. But at Har-mageddon. Many( great multitude) will be brought through on earth( Prov 2:21-22, Matt 24:22) never having to taste death. Then no matter where one stands. Gods kingdom rule will be the only ruling power in existence( Dan 2:44) so on earth( Matt 5:5) is where the great multitude stand before the throne. They will not go to heaven-Rev 14:3--144,000 are BOUGHT from the EARTH. to heaven. The bride of Christ= the little flock( Luke 12:32) not the great multitude( Psalm 37:9-11,29)
