For the LORD of hosts has planned, and who can frustrate it? And as for His stretched-out hand, who can turn it back?
God does what He plans, and nothing can keep Him from it!
Think about who God is. He's the Supreme Being of the universe, the Creator of everything beside Himself, the Author of life. He's omnipotent, all-powerful. If God decides to do something, what could possibly thwart His purpose? Nothing!
Some Christians are afraid of God's power, as if it could mean disaster for them. But only those who are opposed to God's purpose need to fear His power. If you're building your life around God's purposes in this world, then you can be sure that all of God's power stands behind you, ready to support His work through you.
If you don't have a clear sense of what God's purpose is for you, then build your life around the purposes of God that are true for everyone. He wants you to honor Him with your life, to speak of Him to others, to give Him the credit for what He does in your life, and to pursue a deeper relationship with Him each day.
God is reassuring you through this verse today that He's dependable; His promises are reliable; and you don't need to be nervous about following His will in your life. If He is for you, who can be against you?
