Christians are called of God. We are separated from the rest of mankind, redeemed through the blood of Jesus Christ, and cleansed from sin's corruption. Then we are made partakers of the divine nature—all to make us acceptable for the performance of our duties as priests. We have no excuse for drawing back: We have a perfect and eternal High Priest and we have been cleansed and are part of the same Divine Family that He is. Do we not want to draw close to our "Dad"—which is what it amounts to—and do what He says?
Now the priesthood no longer stands before God on behalf of just Israel; now it draws near to God in behalf of all humanity. The purpose of the priesthood is essentially the same as under the Old Covenant, but its labor has been elevated to a spiritual level. We no longer have to burn bulls, goats, sheep, and turtledoves on a burning fire at the door of the Temple. We are the temple! And, in a secondary way, we—like Jesus Christ who went before us—are also the sacrifice that is put on the altar (see Romans 12:1).

The Holy Spirit is the power of God—not a personage, entity, consciousness, or part of the Godhead or a trinity. The Bible speaks of the Spirit as the power or mind of God, the power of love and of a sound mind. It emanates from Him and thus can be said to be "poured out" (Titus 3:5-6), "breathed" (John 20:22), and used to "fill" (Acts 2:4) and "anoint" (Acts 10:38).
