The earth is full Kingdoms and peoples, strong and mighty. The strong have always oppressed the weak and many a times, power in the hands of men is misused. However, all Kingdoms of the earth rise and fall. God, however, has set up His Kingdom that will remain forever; a Kingdom that is stronger than the strongest, greater than the greatest, higher than the highest.
This is what Daniel saw in his dream when he saw a Statue that represented different Kingdoms at different times, but a stone cut from heaven, not by human hands, fell on and crushed all the kingdoms of the earth.
No matter how strong and mighty you feel, you should never forget that power belongs and therefore comes from God . One ought to always humble himself before the Lord.
