The more time you spend with someone, the greater the pain of separation. When you truly love someone, you naturally become excited upon hearing that you will be able to see them for a long time.
What a great and glorious joy it is then, that Christ will never leave us, and He will remain with us into eternity! The faithfulness of Jesus is the greatest comfort to those who have been abandoned by friends, family, and loved ones. Whatever we lose in this life, we gain much more in Christ, and whatever we gain in Him will never go away!
