Lamentations 3:22 and 3:31-33:
22 The steadfast love of the Lord NEVER ceases, his mercies NEVER come to an end.
31 For the Lord will NOT cast off FOR EVER:
32 For if He causes grief, Then He will have compassion According to His
abundant lovingkindness. 33 For He does not afflict willingly Or grieve the SONS OF MEN.…
Every argument against universalism has been addressed on these forums & none have shown Scriptural Universalism is not true. For example:
Psalms 49:19, It cometh to the generation of his fathers, For ever they see not the light.
The Hebrew word mistranslated "For ever" above is Strong's Hebrew word #5331, netsach.
The Hebrew of Psa.49:19 has "until"[5704] "a goal"[5331]:
"netsach {nay'-tsakh}; from 5329; properly, a goal...":

5704: "Short Definition: until":
https://biblehub.com/hebrew/5704.htm
The LXX Hebrew scholars who translated NETSACH in the Septuagint rendered it AION[165] in the Greek OT, meaning literally an "age" or "eon" (The Apostolic Bible Polygot, Greek-English Interlinear, p.794). This Greek-English interlinear says "unto the eon he shall not see light". The Greek OT was the Scriptures most often quoted in the NT & used by the early church.
Here it is translated "permanence":
Psa.49:19 Yet he shall come unto the generation of his fathers; Unto permanence, they shall not see light. (CLV)
permanently, "in a way that lasts or remains unchanged indefinitely"
"the state or quality of lasting or remaining unchanged indefinitely. "the clarity and permanence of the dyes" "
Here netsach is used of finite duration that had already ended & is translated "perpetually":
Amos 1:11 Thus, saith Yahweh, Because of three transgressions of Edom, and because of four, will I not turn it back,—Because he pursued, with the sword, his brother, and stifled his compassions, and his anger tare in pieces evermore, and, his indignation, kept watch perpetually[5331]
There is no endless punishment in Psa.49:19.
...Psalm 86:9
9 All nations whom thou hast made shall come and worship before thee, O Lord; and shall glorify thy name.
Psalm 22:27-28
27 All the ends of the world shall remember and turn unto the LORD: and all the kindreds of the nations shall worship before thee. 28 For the kingdom is the LORD’S: and he is the governor among the nations.
Psalm 72:17
17 His name shall endure for ever: his name shall be continued as long as the sun: and men shall be blessed in him: all nations shall call him blessed.
Psalm 145:9-10
9 The LORD is good to all: and his tender mercies are over all his works.
10 All thy works shall praise thee, O LORD; and thy saints shall bless thee.
Psalm 136:1
O give thanks unto the LORD; for he is good: for his mercy endureth for ever.
Psalm 72:11
Yea, all kings shall fall down before him: all nations shall serve him.
Psalm 102:15
So the nations will fear the name of the LORD And all the kings of the earth Your glory.
Psalm 138:4
All the kings of the earth will give thanks to You, O LORD, When they have heard the words of Your mouth.
Isaiah 60
2"For behold, darkness will cover the earth And deep darkness the peoples; But the LORD will rise upon you And His glory will appear upon you. 3"Nations will come to your light,
And kings to the brightness of your rising.
Isaiah 62:2
The nations will see your righteousness, And all kings your glory; And you will be called by a new name Which the mouth of the LORD will designate.
Revelation 21:24
By its light the nations will walk, and into it the kings of the earth will bring their glory.
This includes everyone in the universe, including the dead and demons:
Rev.5:13 And every creature which is in heaven, and on the earth, and under the earth, and such as are on the sea, and all that are in them, heard I saying, Blessing, and honour, and glory, and power, be unto him that sitteth upon the throne, and unto the Lamb for ever and ever.
John speaks of "every creature" & to emphasize this again he repeats "and all that are in them":
Rev.5:13 And every creature which is in heaven, and on the earth, and under the earth, and such as are on the sea, and all that are in them, heard I saying, Blessing, and honour, and glory, and power, be unto him that sitteth upon the throne, and unto the Lamb for ever and ever.
This worship (v.13) uses the same worshipful words as the redeemed of vs 9-10 use in v.12:
12 Saying with a loud voice, Worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing.
All this being in the context of salvation - "the Lamb that was slain" (v.12 & 13).
Revelation 5:13 speaks of a time beyond the punishment in the lake of fire.
Rev.15:4 Who shall not fear thee, O Lord, and glorify thy name? for thou only art holy: for all nations shall come and worship before thee; for thy judgments are made manifest.
This sounds like just payback, not endless annihilation or tortures:
Rev.18:6 Reward her even as she rewarded you, and double unto her double according to her works: in the cup which she hath filled fill to her double.
Rev.21:5 He who was seated on the throne said, “I am making all new!”
