reading into Scriptures what is not there. For instance, how are you quoting Matthew 25:46 "And these will depart into everlasting cutting-off, but the righteous ones into everlasting life.” as discussing living forever on a paradise earth?
Psalm 37:29The righteous themselves will possess the earth, And they will reside forever upon it.
Personally, I feel the Bible strongly shows that there is no everlasting future for this planet,
Psalm 37:29The righteous themselves will possess the earth, And they will reside forever upon it.
Matthew 25:46 "And these will depart into everlasting cutting-off, but the righteous ones into everlasting life.”
and the expectation of early Christians was heavenly
That is very true but in their hope and expectation of heavenly life did that mean that there was no earthly life…
Philippians 3:8 Why, for that matter, I do indeed also consider all things to be loss on account of the excelling value of the knowledge of Christ Jesus my Lord. On account of him I have taken the loss of all things and I consider them as a lot of refuse, that I may gain Christ 9 and be found in union with him, having, not my own righteousness, which results from law, but that which is through faith in Christ, the righteousness that issues from God on the basis of faith, 10 so as to know him and the power of his resurrection and a sharing in his sufferings, submitting myself to a death like his, 11 to see if I may by any means attain to the earlier resurrection from the dead. 12 Not that I have already received it or am already made perfect, but I am pursuing to see if I may also lay hold on that for which I have also been laid hold on by Christ Jesus. 13 Brothers, I do not yet consider myself as having laid hold on [it]; but there is one thing about it: Forgetting the things behind and stretching forward to the things ahead, 14 I am pursuing down toward the goal for the prize of the upward call of God by means of Christ Jesus.
1 Thessalonians 4:16 because the Lord himself will descend from heaven with a commanding call, with an archangel’s voice and with God’s trumpet, and those who are dead in union with Christ will rise first. 17 Afterward we the living who are surviving will, together with them, be caught away in clouds to meet the Lord in the air; and thus we shall always be with the Lord.
1 Corinthians 15:51 Look! I tell YOU a sacred secret: We shall not all fall asleep in death, but we shall all be changed, 52 in a moment, in the twinkling of an eye, during the last trumpet. For the trumpet will sound, and the dead will be raised up incorruptible, and we shall be changed
Matthew 24:31 And he will send forth his angels with a great trumpet sound, and they will gather his chosen ones together from the four winds, from one extremity of the heavens to their other extremity.
Revelation 20:6 Happy and holy is anyone having part in the first resurrection; over these the second death has no authority, but they will be priests of God and of the Christ, and will rule as kings with him for the thousand years.
If Paul was trying to attain the first resurrection/earlier resurrection which is the upward calling (to heavenly life) and the fact that it mentions that there is a first/earlier resurrection would seem to indicate that there is at least another/2nd resurrection and if so then being that the first is the upward calling (heavenly) then would it not be fair to say that the 2nd is earthly being that it is stated that:
Matthew 5:5 “Happy are the mild-tempered ones, since they will inherit the earth.
Ps. 37:29: “The righteous themselves will possess the earth, and they will reside forever upon it
Psalm 37:11 But the meek ones themselves will possess the earth,
And they will indeed find their exquisite delight in the abundance of
peace.
