English “be revealed” and “the manifestation” emboldened in Romans 8:18 & 8:19 were translated from Greek verb 601 apokalypto and Greek feminine noun 602 apokalypsis respectively. Greek verb 601 apokalypto generically means to take off the cover that is hiding something in order to reveal what is being hidden by the covering. When God, either in spiritual form or in the embodiment of Jesus Christ, is the grammatical subject who performs the action of Greek verb 601 apokalypto it specifically means to remove the flesh thoughts and feelings that cover and hide God’s intrinsic spiritual truth. An analogy might be helpful. In 1John 1:5 it says “God is light, and in him is no darkness at all”. Imagine a wall switch and the ceiling light the wall switch controls. If you were to remove the switch from the wall and connect the two wires together the ceiling light will be on all the time. The wall switch was designed to break the current to the light. God is the light. Flesh thoughts and feelings are the switch. Jesus’ role during this earth age is to remove the flesh thoughts and feelings that cover God’s spiritual light.
Greek feminine noun 602 apokalypsis is the revelation of the thing being revealed by removing the covering that hides and covers what is hidden. Greek verb 601 apokalypto has been translated 4 times into English “reveal” and 22 times into “revealed” in the past, present and future tense. Greek feminine noun 602 apokalypsis was 9 times translated into English “revelation” 2 times into “shall be revealed” 2 times into “revelations” 1 time into “the coming” 1 time into “the appearing” 1 time into “to lighten” 1 time into “Revelation” in Revelation 1:1 and 1 time into “the manifestation” in Romans 8:19 For the earnest expectation of the creature waiteth for the manifestation of the sons of God. Please refer to prior posts regarding Romans 8:14-21 which provide biblical proof that God’s “seven thousand” “election” are also God’s “saints” throughout the bible. The “many brethren” of Romans 8:29 are the “sons of God” of Romans 8:14 and 19. God, either in spiritual form or in the embodiment of Jesus Christ is the grammatical subject who performs the action of Greek verb 601 apokalypto and God’s “seven thousand” “election” are the recipients of the action performed during this earth age. God’s “seven thousand” “election” will superimpose the same action to “the rest” of humanity during the “thousand years” “Lord’s day” that will occur between this earth age and the eternal age that follows.
