Nature shows us what God is like. It's in the Bible, Psalm 19:1, TLB. "The heavens are telling the glory of God; they are a marvelous display of His craftsmanship."
God's power controls nature. It's in the Bible, Matthew 8:26, TLB. "But Jesus answered, 'O you men of little faith! Why are you so frightened?' Then He stood up and rebuked the wind and waves, and the storm subsided and all was calm. The disciples just sat there, awed! 'Who is this, they asked themselves, 'that even the winds and the sea obey Him?'"
Nature proves that God exists. It's in the Bible, Romans 1:20, TLB. "Since earliest times men have seen the earth and sky and all God made, and have known of His existence and great eternal power. So they will have no excuse [when they stand before God at Judgment Day]."
Nature itself is eagerly awaiting its own redemption from the effects of sin. It's in the Bible, Romans 8:19-22, TLB. "For all creation is waiting patiently and hopefully for that future day when God will resurrect his children. For on that day thorns and thistles, sin, death, and decay—the things that overcame the world against its will at God's command—will all disappear, and the world around us will share in the glorious freedom from sin which God's children enjoy. For we know that even the things of nature, like animals and plants, suffer in sickness and death as they await this great event."
