But our citizenship is in heaven, and from it we await a Savior, the Lord Jesus Christ, — Php 3:20

Beloved, we are God's children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is. And everyone who thus hopes in him purifies himself as he is pure. — 1 Jn 3:2-3
