As you read, consider how Scripture describes revelation here:
4 And we are writing these things so that our joy may be complete.
5 This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all. 6 If we say we have fellowship with him while we walk in darkness, we lie and do not practice the truth. 7 But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin. 8 If we say we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
“In one sense God’s disclosure of himself is as universal as *creation itself: ‘The heavens declare the glory of God; the skies proclaim God; the work of his hands’(Ps. 19: 1, NIV).
By observation of the natural *world, Job should have known better than to call God’s known better than to ways into question (Job 38, 40). The things God has created, as people live in symbiotic dependence on them, reveal God’s being and dependence on them, reveal God’s being and even aspects of his nature: ‘Since the creation of the world God’s invisible qualities - his eternal power and divine nature – have been clearly seen, being understood from what has clearly seen, being understood from what has been made, so that men are without excuse” (Rom. 1:20).
*Jesus reasoned from the natural order to *truth about God: ”‘See how the lilies of the field grow . . . If that is how is God clothes the grass of the field, which is here today and tomorrow is thrown into the fire, will he not much more clothe you, O you of little faith?’ (Matt. 6:28, 30). Theologians give the name ‘natural revelation’ to knowledge of God that in theory all people everywhere are capable of inferring from the phenomena of nature and human experience.”
