See earlier post on the difference between chronos and kairos.
Neither ‘chronos’ nor ‘kairos’ are specifically Christian words. Both words were used in non-biblical contexts long before the Christian era. This means that there is nothing inherent in the words themselves which require ‘chronos’ to refer to time on earth, and ‘kairos’ to refer to the timelessness of eternity.
Both words are used in the heavenly context in the New Testament. And both words are used in the earthly context in the New Testament. Listed below are a few examples.
