Mark 9:40 (KJV) says, "For he that is not against us is on our part." This verse is part of Jesus' teaching to his disciples, and it speaks to the inclusive nature of the Kingdom of God.

In this verse, Jesus is addressing his disciples' concern about someone who was casting out demons in his name, but who was not part of their immediate group of followers. The disciples were indignant about this, and they tried to stop the man from doing this work because he was not part of their group. However, Jesus rebukes them and tells them that anyone who is not against them is on their side.

The theme of inclusivity is central to this verse. Jesus is teaching his disciples that the work of God is not limited to a particular group or sect. Instead, anyone who is working in alignment with the Kingdom of God, regardless of their affiliation, is considered to be on their side. This serves as a challenge to the disciples' narrow thinking and calls them to embrace a more open and welcoming attitude towards others who may not fit into their immediate circle.

Furthermore, the context of this verse is important to understanding its full meaning. Jesus' ministry was marked by acts of healing, deliverance, and compassion. He consistently reached out to those who were marginalized and rejected by society, and he demonstrated the expansive nature of God's love and grace. In this context, the verse can be seen as an extension of Jesus' inclusive ministry, as it challenges his disciples to also embody this inclusive spirit in their own interactions with others.

Symbolically, the verse can be seen as a representation of the broader message of the gospel. It speaks to the idea that the Kingdom of God is open to all who are willing to align themselves with its principles of love, justice, and mercy. It emphasizes the idea that God's grace is not limited to a select few, but is available to all who seek it.

In addition, the verse also carries a message of unity and cooperation. By affirming that those who are not against them are on their side, Jesus is highlighting the importance of working together towards a common goal. This can be applied to the broader Christian community, as it calls for unity and collaboration among believers, regardless of denominational differences or theological perspectives.

Overall, Mark 9:40 (KJV) is a powerful reminder of the inclusive and expansive nature of the Kingdom of God. It challenges us to embrace a more open and welcoming attitude towards others, to recognize the work of God in diverse places and people, and to strive for unity and cooperation within the Christian community. It is a call to embody the love and grace of God in our interactions with others, and to recognize the common ground we share as followers of Christ.
