Why would Jesus promise us something that cannot endure until the end? Why would he teach us to trust him and then make keeping our salvation dependent on us? Is our debt paid for or not? Did the payment that Jesus made include payment for all past, present and future sins?
The Bible speaks of “life everlasting” (Luke 18:30 KJV). Nothing is temporal about everlasting? The Bible Say’s “He that believeth hath eternal life” (John 6:47 ASV). How can that which is eternal be temporal? Why would the word eternal that describes God no longer be eternal when it describes our destiny with him? It wouldn’t. In Christ we can have life everlasting.
