The Lord Jesus Christ will come again, embodied, to judge all people, who will receive what id due for what has been done in their body, whether good or evil.
We do not know when Christ will come again, but we know we need to be prepared for that day and that the time to prepare is today.
"Come, let us walk in the light of the LORD... Stop regarding man in whose nostrils is breath, for of what account is he?” – Isaiah 2.5,22
