Could it be that living under an open heaven is ultimatley living with a conscience sense that we are “Beloved.”
Matt. 3:16 After being baptized, Jesus came up immediately from the water; and behold, the heavens were opened, and he saw the Spirit of God descending as a dove and lighting on Him, 17 and behold, a voice out of the heavens said, “This is My beloved Son, in whom I am well-pleased.”
Luke 3:21 Now when all the people were baptized, Jesus was also baptized, and while He was praying, heaven was opened, 22 and the Holy Spirit descended upon Him in bodily form like a dove, and a voice came out of heaven, “You are My beloved Son, in You I am well-pleased.”
John 1:51 And He *said to him, “Truly, truly, I say to you, you will see the heavens opened and the angels of God ascending and descending on the Son of Man.”
The Holy Dove, who is the Himself the infinite God, rests on us, and is constantly gushing into our hearts the sound of The Father’s voice calling us “Beloved“.
Rom.5:5,… and hope does not disappoint, because the love of God has been poured (gushed, and continually gushes) out within our hearts through the Holy Spirit who was given to us.
When people speak of living under an open heaven, they are speaking of living acutely conscience of His voice, power, and favor. Surely, living under the echoing sound of His delight over us, by The Holy Spirit, is the foundation of all faith that believes in, and receives His power and favor. According to Romans 8, to know that nothing can separate us from the love of Christ, is the prerequisite to live as overwhelming conquers at all times in this life.
