Notes from 1 Peter 2:11
As believers, we are "temporary residents and foreigners" in this world because our real home is with God. Heaven is not the pink-cloud-and-harp existence popular in cartoons. Heaven is where God lives. Life in heaven operates according to God's principles and values, and it is eternal and unshakable. The Kingdom of Heaven came to earth in the symbolism of the Jewish sanctuary (the Tabernacle and Temple), where God's presence dwelt. It came in a fuller way in the person of Jesus Christ: "God with us." It spread through the entire world as the Holy Spirit came to live in every believer.
Someday, after God judges and destroys all sin, the Kingdom of Heaven will rule every corner of this earth. John saw this day in a vision, and he cried out, "Look, God's home is now among his people! He will live with them, and they will be his people. God himself will be with them" (Revelation 21:3). Our true loyalty should be to our citizenship in heaven, not to our citizenship here, because the earth will be destroyed. Our loyalty should be to God's truth, his way of life, and his dedicated people. Because we are loyal to God, we often will feel like strangers in a world that would prefer to ignore God.
