Not by Might
"This is the word of the LORD to Zerubbabel: 'Not by might nor by power, but by My Spirit,' Says the LORD of hosts."
God’s word came to His people at a critical time. They were a despondent, disillusioned people who faced a daunting task. They had been exiled in Babylon for seventy years. During this time they had witnessed the strength of the most dominant military power in their world. They had watched the Babylonian army marching off to conquer other nations. They had seen the wealth and splendor of the Babylonian king. When Babylon was in turn conquered by the Persians, the Israelites saw an even greater superpower emerging on the world stage. They lost heart when they compared their own weakness and captivity with the enormous strength and wealth of the superpowers of their day.
As the Israelites returned to Jerusalem after seventy years in captivity, they found their city in ruins. Their magnificent temple had been destroyed. The city walls had been torn down. They had no resources to rebuild their splendid city. As these former refugees looked at the mammoth task before them, they realized their poverty and weakness, and they became greatly dismayed. Then came God’s word! He promised that they would, indeed, rebuild their city. But, He told them, the rebuilding would not be accomplished by their own power and resources but by His Spirit. As long as they had God’s Spirit, they had everything they needed.
There will be times when obeying God will lead you to impossible situations. If you look at your own skills, knowledge, and resources, you will become discouraged. However, when you became a Christian, God placed His Spirit within you. You now have the resources of heaven at your disposal. The success of your endeavors will not depend on the way you use your own resources but on how you obey the Spirit of God.
