I am reminded of men like Charles deFocould who longed to "cry the gospel" with his life. I think that sometimes we can get distracted by things that just aren't primary. We need to keep the kingdom of God first and foremost in our life and in our minds. We need to be looking at the ways that we are living into the kingdom and looking for the kingdom reality in our midst. I hear far too few Christians speak of the kingdom of God.
We speak of the church, the work of the church, society, even the gospel but yet not the kingdom. Far too few Christians seem to grasp the fact that Jesus came to preach the good news of the present availability of the kingdom of God. This is reality and it is this reality that we should base our lives and seek to live more deeply into. It is what we pray "thy kingdom come, thy will be done". We are people of the kingdom, servants of the king. A disciple is a person who is learning to live in the kingdom reality by learning from the one who brings the kingdom, Jesus of Nazareth.
This is living the gospel, it is a call to surrender ourselves to a God who gave himself for us.
