- In keeping with the analogy of God's Holy Spirit as our Breath of Life, He appears as wind. This alludes back to the creation account where YHWH God breathes the breath of life into Adam who then becomes a living soul. And it fulfills Jesus' prophetic actions when he first appeared to the disciples after his resurrection, in the upper room, and breathed on them, saying: "Receive the breath of life."
And as The Light of the world He appears as "tongues of fire." This analogy appears in many other places as well, such as Moses' face glowing after spending time in God's presence, and Jesus on the mount of transfiguration, where Peter, James and John get a glimpse of Jesus' glorified state.

Then Peter continued preaching for a long time, strongly urging all his listeners, "Save yourselves from this crooked generation!"  Those who believed what Peter said were baptized and added to the church that day-about 3,000 in all.
- The "turn or burn!" style of Save Yourself From Imminent Destruction message! As time goes on and we see that Christ's return may not be quite as Peter first imagined it, how has our Christian meapssage developed and grown? Or has it? Is this really all The Good News is about? Save your backside!
