who by the power of God are guarded through faith for a salvation ready to be revealed in the last time.
We cannot have this manifestation of the sons until the last day. Paul says in 2 Timothy 4:8, "Henceforth there is laid up for me a crown of righteousness, which the Lord, the righteous judge, shall give me at that day: and not to me only, but unto all them also that love his appearing." Paul says this would be given to us in "that day." The apostle Peter here suggests a similar idea. Salvation is equated with the inheritance, which is reserved in heaven for the faithful. He makes it clear that there is no inheritance nor salvation for those who cease to believe or act like the sons of God.
