Salvation wrongly might be understood as an something escaping this earth to reach invisible spiritual realm. Spiritual life has nothing to do with invisible world. In fact spirituality has something with real life of ordinary lives in this earth correctly. And the salvation is from the rule or bind of the Satan not from this earth.
He who believe in me, though he were dead, yet shall he live: And whosoever live and believe in me shall never die. Do you believe this? (John11:25,26)
