What about This? What about That?
The whatabouts are like flies to swat. They generally are passages that don't say anything like "lose salvation" or "lose faith." But people bring them up. When will we hear "WhatAboutThe natives in Bongo Bongo that never heard?"
Best to focus on what is actually said about salvation & eternal life.
Nay, in all these things we are more than conquerors through him that loved us. For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, nor powers, nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
Blessed be the God and Father of our Lord Jesus Christ, who according to his great mercy begat us again unto a living hope by the resurrection of Jesus Christ from the dead, unto an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you, who by the power of God are guarded through faith unto a salvation ready to be revealed in the last time.
"I shall dwell in the House of the LORD forever."
Anyone read Ps 23 lately?
