'Of the World' in the Bible

For we who believe [that is, we who personally trust and confidently rely on God] enter that rest [so we have His inner peace now because we are confident in our salvation, and assured of His power], just as He has said,“As I swore [an oath] in My wrath,They shall not enter My rest,”[this He said] although His works were completed from the foundation of the world [waiting for all who would believe].

Otherwise, He would have needed to suffer over and over since the foundation of the world; but now once for all at the consummation of the ages He has appeared and been publicly manifested to put away sin by the sacrifice of Himself.
