TSK · Luke 22:43

Behold, you have instructed many, you have strengthened the weak hands.

Behold, one in the likeness of the sons of men touched my lips: then I opened my mouth, and spoke and said to him who stood before me, my lord, by reason of the vision my sorrows are turned on me, and I retain no strength.

and said to him, "If you are the Son of God, throw yourself down, for it is written, 'He will put his angels in charge of you.' and, 'On their hands they will bear you up, so that you don't dash your foot against a stone.'"

Or do you think that I couldn't ask my Father, and he would even now send me more than twelve legions of angels?

but I prayed for you, that your faith wouldn't fail. You, when once you have turned again, establish your brothers."

Without controversy, the mystery of godliness is great: God was revealed in the flesh, justified in the spirit, seen by angels, preached among the nations, believed on in the world, and received up in glory.

Aren't they all serving spirits, sent out to do service for the sake of those who will inherit salvation?
