Like Paul, John begins his “letter” with a benedictory greeting: Grace and peace. The blessings does not end until verse 8, and it is chiastically structured:
A. From Him who is, was, coming
B. From seven Spirits
C. From Jesus Christ
D. Glory to Him
C’. Behold, He comes (who? see C: Jesus)
B’. Every eye sees, they pierced, they mourn (cf. “spirit” poured out in Zechariah 12:10-14, quoted here)
A’. Alpha and Omega; the Is, Was, Coming
