Numerous proverbs speak about the character, actions, and effects of the lives of kings. Rather than applying these as a means of judging our current civil leaders, can I suggest that we apply them to our own lives, since we are "a royal priesthood" (1 Peter 2:9), made by the Lamb to be "a kingdom" that will "reign upon the earth" (Revelation 1:6; 5:9,10)?
Proverbs 8:15; 14:28,35; 16:10,12-15; 19:12; 20:2,8,26,28; 21:1; 22:11,29; 24:21; 25:2,3,5,6; 29:4,14; 31:3,4.
After all, the kings of Israel were but a foreshadowing in their office of the King of kings, Jesus Christ. Our authority (Matthew 16:19; John 20:21-23) is not of us, but solely an extension of the Father's through the Son, exerted only in the power of the Holy Spirit through the Body. This is Kingdom authority and power, not of us.
We, as royalty, have an obligation to mirror the character, actions, and effects of the Absolute Sovereign. Perhaps the Proverbs of the Court can be guides for us as we steward the Kingdom.
