I've never spoken with an angel, though one time I felt the awesome weight and glory of God's presence in an angel in my bedroom as I kneeled in prayer. I kept my eyes closed, good Baptist that I was at the time, so I never knew if it was an angel. (I now am reasonably confident it was.)

God's idea of redemption is community-shaped.

The assumption that the gospel can be reduced to a note card is already off on the wrong track.

The angels of the Bible terrify the humans to whom they visit; they startle and scare and even stun the humans. Why? Because in the Bible angels are colossal figures, fiery in light and, more often than not, overwhelming in their power. Angels, then, in the Bible are supernatural beings that humble us in their presence.

God's love entails a covenant commitment on the part of with us, and that covenant commitment means a promise to be with us and for us, and God's covenant is shaped toward our redemption.

In the Bible angels speak and humans speak back to them. This is the case with Mary in Luke 1. The angel speaks, Mary questions, and it goes back and forth. Abraham speaks with angels. So I would contend the Bible has enough evidence of angels speaking and humans speaking that speaking with an angel today would be reasonable. I've heard enough stories and read such that confirm that Christians today do speak with angels.

Jesus wanted far more than to be accepted into one's life. He wanted to take over, and his essential call was to trust him enough to surrender one's entire being to him.
