King of Kings, ruler of all creation
The Christian faith is a religion of world domination.
When Jesus left His apostles, He told them that all authority in Heaven and Earth has been granted to Him. (See Matthew 28:18-20.) The Apostle Paul tells us in Philippians 2:10-11 that every knee shall bow to Jesus Christ. Jesus tells us in Matthew 10:34 that He "came not to send peace, but a sword."
It is true that the weapons of our warfare are not physical, but spiritual. But we should not forget that the Christian life is one of warfare - against our own sin nature and against spiritual wickedness in high places. (Ephesians 6:12.) And it is a war we are destined to win. We should not for a second doubt that God is capable of sending revival to our nation or across the world, because He is infinitely powerful and His Spirit can convert even the most obstinate and cold heart to believe on His Son.
Jesus Christ is gentle and lowly, and humble of heart. He takes our burdens on Himself. For a repentant sinner, this truth is a blessing and a comfort. But that is not the encouragement that Christians need today in an increasingly post-Christian culture. Jesus is also the King of Kings, mighty in battle (Psalm 24:8) who is sovereign over all creation. Nothing escapes His notice.
A friend of mine used to say that no matter what setbacks Christians face in the present, he knows we will win in the end because he has read the end of the book. Christians in the pagan Roman Empire may have despaired as they were being fed to lions or tortured to death by evil men in authority. But two thousand years later, the Roman Empire is long gone and the Christian faith is still spreading across the world.
We need to stop being shy about the sovereignty of God, and that starts by taking the Great Commission seriously. When Jesus told us to disciple all of the nations and teach them to obey His commandments, He did not give us a command that He would not grant the power to obey. As the Apostle Paul tells us in Romans 8:31-32, if God is with us, no one can stand against us.
