The church of Jesus is not the kingdom of God. But, certainly, the church is called to represent the kingdom in this world.
Insofar as we represent the kingdom, we succeed with our mission. When we fail to do so, we fail in our mission.
When there are divisions, we fail.
When there are power struggles, we fail.
When our focus is on humans rather than God, we fail.
We fail a lot. We also succeed sometimes. Let us readjust and represent the kingdom. This is vital. We need the help of God to do it.
