27 Then Peter answered and said to Him, “See, we have left all and followed You. Therefore what shall we have?” 28 So Jesus said to them, “Assuredly I say to you, that in the regeneration, when the Son of Man sits on the throne of His glory, you who have followed Me will also sit on twelve thrones, judging the twelve tribes of Israel.” (Matthew 19:27–28, NKJV)
The faithful apostles had left their professions and possessions to follow Jesus (Mark 1:16-20; Luke 5:11). Their subsequent work in the kingdom of God justified their sacrificial faith. Christ gave them authority to judge among the “twelve tribes of Israel” (i.e., the people of God, Romans 9:6-8; Galatians 6:16) by the gospel they proclaimed (Mark 16:15; 2 Thessalonians 2:15; Romans 2:16). Christ’s reign and their authority to judge coincide with “the regeneration,” a reference to the time of salvation which began in Acts 2 and continues until His return (Acts 2:29-41; 2 Corinthians 6:1-2; 5:17). Even as the Son of Man now reigns in glory, the apostles’ word is the standard of authority by which souls are regenerated (born again, John 3:3-5; 2 Corinthians 5:17-21). We take comfort and courage in knowing that when we sacrifice all to follow Jesus, He has prepared eternal glory with Him for us (Colossians 3:4).
