No Exams Necessary
China invented the exam system in 700 AD. Those passing the exams, rather a prince or a poor man, could reach the heights in the Empire of China. The person could become an adviser to the Emperor, and could be in the throne room of China. Yet the Christian without passing a kindergarten quiz is seated on the throne of God with Christ!
But God, being rich in mercy, because of His great love with which He loved us, even when we were dead in our trespasses, made us alive together with Christ (by grace you have been saved), and raised us up with Him, and seated us with Him in the heavenly places, in Christ Jesus, in order that in the ages to come He might show the surpassing riches of His grace in kindness toward us in Christ Jesus. (Eph 2:4-7)
Showing the marvel of his grace and the infinite value of Christ, God gives the illiterate, the fool, and especially the sinner the greatest honor possible of being seated next to Christ on Heaven's throne. In this way, God the Father shows the surpassing riches of his grace towards us as he will through all eternity.
