"'You, O king, saw a messenger, a holy one, coming down from heaven and saying, "Cut down the tree and destroy it, but leave the stump, bound with iron and bronze, in the grass of the field, while its roots remain in the ground. Let him be drenched with the dew of heaven; let him live like the wild animals, until seven times pass by for him."'" NIV translation
Now, the bad news is that the tree is to be cut down. God is good and even with this bad news comes hope. We see that the roots of the tree are not removed but instead are only restrained by the iron and bronze. In this, we see that God is in control of all things and all things happen in His time.
