Would you please explain what Jesus was referring to as “the end of the age” in this parable? Is it the end of this age, which will cease at the end of the Tribulation, and then goes right in to the 1000 year reign of Christ? Or is it referring to the end of the 1000 years just before going into eternity? Verse 43 says “Then the righteous will shine like the sun in the kingdom of their Father..” Is this referring to the Millennium or eternity?
The Age Jesus referred to in Matthew 13:36-43 is what we call the Age of Law that will conclude with the Great Tribulation.
The wicked will be burned in the fires of judgment and the righteous will be welcomed into the Millennial Kingdom. The phrase “righteous will shine like the sun” is very similar to Daniel 12:3, where the context is the resurrection of Old Testament believers at the time of the 2nd Coming.
Those who are wise will shine like the brightness of the heavens, and those who lead many to righteousness, like the stars for ever and ever.
