And one of the four living creatures gave to the seven angels seven GOLDEN BOWLS
These are the four living creatures who are introduced in Revelation 4:6,7 and are active in the pronouncement of the seal judgments (Revelation 6:1-8).
Creation has been waiting for the judgments starting by this mixing of the WRATH of GOD with the plagues (Romans 8:19-21).
GOLD denotes diety which ties it directly to the WRATH of GOD. The bowls also were bronze utensils used in temple worship of this God (Exodus 27:1-3-8 and Amos 6:1-6-7).
Contrast these bowls with the ones in Revelation 5:8.
full of the WRATH OF GOD, who lives forever and ever.
We have no concept of the full WRATH OF GOD because we know Him as a God of LOVE. This WRATH may be 7 different kinds of WRATH or, more likely, the FULL WRATH OF GOD is mixed in with each of the plagues the seven angels are carrying (previous verse).
"forever and ever" is a given for God. This implies that the WRATH of GOD existed before the creation of this earth. What is hard for us humans to grasp is how the TOTAL LOVE and FULL WRATH of GOD has coexisted within God "forever and ever". It is one of the deep mysteries of GOD.
