Such Great Heights lyrics by Postal Service

I think he means he's above all his fans who listen and don't believe in our Lord, they want him to come down to their level on Earth but he is part of a new world with God. He is on a different level and knows he is better off staying there where he has no troubles. He wants the person he is referring to in the song to hear his words and his testimony of God, that He has a plan for everybody, and maybe the words will lead this person to "home" which is Heaven and guide this person to God and his level with God if he or she believes.

I think this song means that someone was going through a hard time.Like their head was in the clouds or in this case "space" and they had support from their loved one's who were on supposedly on "earth".
And that when they were ready to express their feelings to anyone they would realize that their loved ones had been waiting or again in this case "waving" waiting for them to come down now.
I messed up on the first one.
