I agree that Jesus is speaking much about "earthly" blessings. This is not the same as if Jesus was talking about a paradise earth full of "immortal" human bodies though or sadly, it is simple a blessing like if you honour your parents you will inherit the earth.
BUT Jesus certainly did not only speak of a "heavenly" hope too. All his parables speak of an strongly "earthly" blessings for men on earth, it showes that Jesus' understanding of the kingdom of god had an earthyl note. Perhaps expressed with the words of the swiss reformed theologian Leonhard Ragaz and the catolic philospher and priest Urs Eigenmann https://en.wikipedia.org/wiki/Leonhard_Ragaz#
Jesus understanding of "EARTH"ly blessing might have been: "the kingdom of God, the Righteousness for the EARTH" (book title by Urs Eigenmann). If you think of all the earthly blessings that are in the parables and the sermon of the mountain that is clear. The Jewish hope was primarily a blessing for MEN on Earth and secondly the eternal completion in community with god.
He testified as a holistic liberation from material need and disease, from political oppression and social exclusion, as well as from religious ostracism and demons. Despite the central concern of Jesus, the Kingdom of God in the Great Churches and their school-theologies did not play a role for centuries, or it was privatized, spiritualized and misrepresented.
On the other hand, the central position of the Kingdom of God is emphasized in the message of Jesus, and is confirmed by his biblically attested content and complex structure. The Kingdom of God can be understood as a universal-solidarity community of people, in which all those who are in need of material, social and cultural-religious needs recognize themselves.
Against this background, the question of God is posed in the horizon of the Kingdom of God, the criteria for a kingdom of god compatibility assessment of the church and society are developed as well as the dimensions of a kingdom-God-spirituality and mysticism. This is in the knowledge that all efforts in the sense of the kingdom of God are to be seen in the horizon of his fulfillment promised as the gift of God.
