The highest heavens belong to the LORD, but the earth he has given to man. - Psalm 115:16

I heard this verse recently and it really spoke to me. Since we know that God will always keep His Word, this verse explains why bad things happen in the world. These bad things were never meant to happen, but man allowed sin to corrupt God's creation. Here's the passage from the Message Bible:

12-16 O God, remember us and bless us, bless the families of Israel and Aaron. And let God bless all who fear God— bless the small, bless the great. Oh, let God enlarge your families— giving growth to you, growth to your children. May you be blessed by God, by God, who made heaven and earth. The heaven of heavens is for God, but he put us in charge of the earth.

God put us in charge of the earth. We have the authority on this earth. Now, let's bring this to the New Testament to confirm the authority given to man. While Jesus was on the earth, He was given authority for both heaven and earth:

Then Jesus came to them and said, "All authority in heaven and on earth has been given to me. - Matthew 28:18
