The "wrath of the Lamb" vs. the "wrath of God".

While John 1:1 (among other verses) speaks to the Lord Jesus' deity, the title "God" usually refers to the Father in Scripture:

Titus 1:1- "Paul, a servant of God, and an apostle of Jesus Christ, according to the faith of God's elect, and the acknowledging of the truth which is after godliness;"

Hebrews 13:20- "Now the God of peace, that brought again from the dead our Lord Jesus, that great shepherd of the sheep, through the blood of the everlasting covenant,"

James 1:1- "James, a servant of God and of the Lord Jesus Christ, to the twelve tribes which are scattered abroad, greeting."

1 Peter 1:3- "Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead,"

1 Peter 5:10- "But the God of all grace, who hath called us unto his eternal glory by Christ Jesus, after that ye have suffered a while, make you perfect, stablish, strengthen, settle you."

2 John 1:3- "Grace be with you, mercy, and peace, from God the Father, and from the Lord Jesus Christ, the Son of the Father, in truth and love."

Jude 1:1- "Jude, the servant of Jesus Christ, and brother of James, to them that are sanctified by God the Father, and preserved in Jesus Christ, and called:"

Revelation 1:1- "The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified it by his angel unto his servant John:"

Revelation 21:22-23: "And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it. 23 And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof."

Remember, John was weeping because "no one was found worthy to open and read the book, neither to look thereon" (Revelation 5:4), but then we see that the Lamb "came and took the book out of the right hand of him that sat upon the throne" (Revelation 5:7). Then we see the 4 beasts and 24 elders fall down before the Lamb (Revelation 5:8) singing the "new song", about how the Lamb has redeemed every kindred, tongue, people, and nation "to God" (Revelation 5:9).

So John certainly makes a distinction between "the Lamb" and "God". Again, I'm certainly not saying that the Lamb isn't God the Son, but Scripture refers to the Lord Jesus as the only "mediator between God and men" (1 Timothy 2:5), so again, "God" usually refers to the Father in Scripture.

So if John clearly makes a distinction between "the Lamb" and "God" ("him that sat upon the throne"), Why are many trying to conclude that "the wrath of the Lamb" (Revelation 6:16) and "the wrath of God" (Revelation 15:1, 15:7, and 16:1) are one and the same (even though the trumpet judgments aren't even referred to as "wrath")?

It's one of the strongest arguments as to why the judgments aren't merely simple chronological events (the 7 seals followed by the 7 trumpets followed by the 7 vials). That's overly simplistic.

The men of the Earth are frantic after the heavenly signs (6th seal) not because they see all of the trumpets and vials ahead, but rather because they see the 7th seal, 7th trump, and 7th vial immediately ahead, culminating in the literal return of the Lord ("parousia"), which includes "the wrath of the Lamb" (see 2 Thess 1:7,8; 2 Thess 2:8; and Revelation 19:11-21), and is the same moment that all of the elect are raptured/resurrected.

So the "wrath of the Lamb" IMMEDIATELY follows the 7th seal, 7th trump, and 7th vial (which occur simultaneously with each other). It therefore seems as if the "wrath of the Lamb" is the "Day of the Lord".
