If we were called to live like kings so that we could shout orders, dictate, and rule the land, we'd all be fighting over who got to wear the crown. We would fully, wholly, and quickly embrace our new majestic mantle. But as Christians, as "a kingdom of priests, God's holy nation, His very own possession", we are called to something entirely different.
Peter spelled this out for us in plain terms:
"And now God is building you, as living stones, into His spiritual temple. What's more, you are God's holy priests, who offer the spiritual sacrifices that please Him because of Jesus Christ.... You are a kingdom of priests, God's holy nation, His very own possession. This is so you can show others the goodness of God, for He called you out of the darkness into His marvelous light." (1 Peter 2:5, 9)
YES, we are children of the King! But we follow a king who chose not to have people fall at His feet, but to get on His knees and wash theirs. He has claimed us, bought us with the price of His own body, and called us "so that" we can show others the goodness, mercy, kindness, and love of the God of the Universe. That's the mission. And any Christian that says, "I just don't know what my purpose is in life" - you need not look any further! SHOW OTHERS JESUS!
Think about it.
What are some simple ways that you can carry out this calling today?
How can you show the world a different kind of king?
