It is, of course, very significant that in requesting direction concerning the possibility of becoming a minister, you are guided to Psalm 121.
I lift up my eyes to the hills.
From whence does my help come?
My help comes from the Lord, who made heaven and earth.
He will not let your foot be moved,
he who keeps you will not slumber.
Behold, he who keeps Israel will neither slumber nor sleep.
The Lord is your keeper; the Lord is your shade on your right hand.
The sun shall not smite you by day, nor the moon by night.
The Lord will keep you from all evil; he will keep your life.
The Lord will keep your going out and your coming in
from this time forth and for evermore (RSV).
The aspect of God that is described in the Hebrew Bible as the Lord is called the Christ in the writings of the New Testament. It refers to the Presence and Power of God within each of us—our true spiritual identity, our unique and unbreakable Oneness with the Allness of that which we call God.
Psalm 121 is called "A Song of Ascents"—an affirmation of our great journey upward in consciousness to the point at which we achieve full expression of that indwelling Christ Presence. What your guidance is telling you, I think, is that that must be the Source of your ministry. Training, licensing, ordination—these may be important steps in your ascent. But your true calling—your own ministry—can only be truly sourced from the Christ within you. As long as you are conscious of that Christ Presence, your path will be safe "from this time forth and for evermore."
