Before giving accusing God of relinquishing authority, we should read this:
And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses, by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross. He disarmed the rulers and authorities and put them to open shame, by triumphing over them in him. (Colossians 2:13-15 ESV)
This has nothing to do with the issue. When God created mankind, He gave man authority over His creation.
Gen 1:26-31
Then God said, Let Us make man in Our image, according to Our likeness; and let them rule over the fish of the sea and over the birds of the sky and over the cattle and over all the earth, and over every creeping thing that creeps on the earth. 27God created man in His own image, in the image of God He created him; male and female He created them. 28God blessed them; and God said to them, Be fruitful and multiply, and fill the earth, and subdue it; and rule over the fish of the sea and over the birds of the sky and over every living thing that moves on the earth. 29Then God said, Behold, I have given you every plant yielding seed that is on the surface of all the earth, and every tree which has fruit yielding seed; it shall be food for you; 30and to every beast of the earth and to every bird of the sky and to every thing that moves on the earth which has life, I have given every green plant for food; and it was so. 31God saw all that He had made, and behold, it was very good.
As if that isn't enough proof, let's review Psa 8:4-9
4 What is man that You take thought of him,
And the son of man that You care for him?
5 Yet You have made him a little lower than God,
And You crown him with glory and majesty!
6 You make him to rule over the works of Your hands;
You have put all things under his feet,
7 All sheep and oxen,
And also the beasts of the field,
8 The birds of the heavens and the fish of the sea,
Whatever passes through the paths of the seas.
9 O LORD, our Lord,
How majestic is Your name in all the earth!
Which was quoted by the writer of Hebrews 2:5-8
5For He did not subject to angels the world to come, concerning which we are speaking. 6But one has testified somewhere, saying,
What is man, that You remember him?
Or the son of man, that You are concerned about him?
7 You have made him for a little while lower than the angels;
You have crowned him with glory and honor,
And have appointed him over the works of Your hands;
8 You have put all things in subjection under his feet.
For in subjecting all things to him, He left nothing that is not subject to him. But now we do not yet see all things subjected to him.
Your view of God's "total" sovereignty doesn't have a leg to stand on.
God, in His perfect sovereignty, has delegated much responsibility to mankind.
In no way did this lessen His sovereignty. But apparently RT doesn't understand this.
