If we hope to demonstrate the level of excellence modelled by Jesus Christ, then we’ll have to come to terms with the kingdom we are going to serve: the eternal kingdom our Lord told us to seek (Matthew 6:33) or the temporal kingdom of today.
Generally speaking, God’s kingdom is a synonym for God's rule. Those who choose to live in His kingdom (though still very much alive on Planet Earth) choose to live under His authority.
For centuries God has been at work re-establishing His rulership. Jesus’ words describe the problem: "No one can serve two masters; for either he will hate the one and love the other, or he will hold to the one and despise the other,” (Matthew 6:24).
The kingdom is the invisible realm where God rules as supreme authority. Only by letting Him reign in your life can you experience true excellence.
