"Therefore, you kings be wise, be warned you rulers of the earth. Serve the LORD with fear and celebrate his rule with trembling." Psalms 2:10-11 (TNIV)
This sounds like a pretty clear warning to me. The LORD is the one is charge, not the rulers of the world. They need to serve Him and follow His plans. No matter what the rulers of this world plan, ultimately they will not have success. Oh, it may seem that way for a while. See my earlier post.
God is ultimately in charge. Remembering that helps me breathe easier and keeps my blood pressure down no matter what is going on the world.
