Jesus provides his presence.
Something to think about
There are two points in verse four. When we come before a judge, whether in a civil or a criminal matter or even in a disciplinary matter at the place of work, it is re-assuring to have somebody else to take us through the procedure, to accompany us, comfort us and speak on our behalf.
Jesus had the authority to send the Holy Spirit and in doing so, did not leave us alone, but left us with the best comforter, helper and advocate. In sending the Holy Spirit, Jesus provides his presence to continue to empower and strengthen all those who advocate for justice and fullness of life for all.
