The heavenly calling vs. the earthly hope — two different destinies in scripture?

Romans 8:15-16: "The spirit itself bears witness with our spirit that we are God's children." A direct internal confirmation — not a church decision. The "little flock" of Luke 12:32 receives the Kingdom. The "great crowd" of Revelation 7:9 survives and lives on earth. Philippians 3:14: Paul calls his calling "the upward call" — suggesting not everyone has it. Are these two groups with genuinely different hopes, or two names for the same group?
