a ministry of presence

The one phrase that describes the ministry of Chaplains in our culture today is "ministry of presence".  Whether they are institutional or military chaplains, their presence brings the physical reminder of the activity of God in the life of persons.  We have a 24/7 Chaplain with us known as the Holy Spirit.  Jesus mentioned His unique function coincidentally in verse 26 of both chapter 14 and 15. 
John 14:26 (NIV)
26 But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.
John 15:26 (NIV)
26 “When the Advocate comes, whom I will send to you from the Father—the Spirit of truth who goes out from the Father—he will testify about me.
We have the help of the Spirit 24/7 to guide, teach and comfort us!  Praise God!
