Another interpretation: It does not say here "Speak to the children of Israel, and let them take a portion (terumah)," but rather "And let them take a portion for Me" (Exodus 25:2). Every matter concerning which "for Me" is said endures in this world and in the world to come.
The Offering Marked For Me Endures in Both Worlds
Yalkut Shimoni on Torah 363:7
דָּבָר אַחֵר, דַּבֵּר אֶל בְּנֵי יִשְׂרָאֵל וְיִקְחוּ תְּרוּמָה אֵין כְּתִיב כָּאן אֶלָּא וְיִקְחוּ לִי תְּרוּמָה, כָּל דָּבָר שֶׁנֶּאֱמַר בּוֹ לִי, בָּעוֹלָם הַזֶּה וּבָעוֹלָם הַבָּא.
