Psalm 96:12-13 says, ‘All the trees of the forest will sing for joy; they will sing before the Lord, for he comes, he comes to judge the earth.’ Isaiah 55:12 says, ‘The mountains and the hills will burst into song before you, and all the trees of the field will clap their hands.’
If you put seeds into a pot of soil and then put it away in the dark, away from the sun, the seeds go into dormancy. They can’t grow to their potential. But if you bring the pot with seeds into the presence of the sun, all that has been locked within them bursts forth. The Bible says that everything in this world – not just we human beings but even the plants, the trees, the rocks – is dormant. These things are just shadows of what they have been, would be, and will be in the presence of their Creator. When the Lamb of God presides over the final feast and the presence of God covers the earth again, the trees and the hills will clap and dance, so alive will they be. And if trees and hills will be able to clap and dance in the future kingdom, picture what you and I will be able to do.
