GOD is Invisible. Heaven is Invisible. Angels are Invisible, Demons are Invisible, Our inner man is Invisible; only for Now, my brother, my sister and my dear friend because we are still in the Natural or Physical realm but they are in Spirit or Eternal. Someday we will also slip in to that realm of Eternity where we came from; World calls it Death and end of our Existence whereas GOD calls it Home coming and Beginning of an Awesome Never Ending Life in Heaven with GOD with our Eternal: Rewards, Treasures, Inheritance provided WE listen to HIM/BIBLE now, to DO what it says before WE lose our Right to CHOOSE or DIE [Matthew 5.18], [Ecclesiastes 12.7 & 13-14], [John 6.27-29], [Matthew 6.19-20], [1 Peter 1.4]. My friend what is Seen is temporary, Unseen is Eternal [2 Corinthians 4.16-18]. So, Listen to GOD/BIBLE now to be: SAVED, Baptized, Sanctified and Fruit bearing [Revelation 3.20], [Romans 10.9-10]. Truth. Wisdom. Choice.
