We long for a political system that will be just and perfect, but it will never happen in this life. Jesus came not to fix everything in this world, but to open for us a better one in heaven. The effects of original sin are still in this world, and it can never be perfect, but if we can be life Jesus, not grasping for power but humbling ourselves for the sake of others, we will join him in heaven.
Based on Philippians 2:5-11
Let the same mind be in you that was in Christ Jesus,
who, though he was in the form of God,
did not regard equality with God
as something to be exploited,
but emptied himself,
taking the form of a slave,
being born in human likeness.
And being found in human form,
he humbled himself
and became obedient to the point of death—
even death on a cross.
Therefore God also highly exalted him
and gave him the name
that is above every name,
so that at the name of Jesus
every knee should bend,
in heaven and on earth and under the earth,
and every tongue should confess
that Jesus Christ is Lord,
to the glory of God the Father.
