We all have things that come against us in life that look permanent—a child who's off course, an addiction, a health issue. It seems so big, so intimidating. It's easy to be overcome and think it will never turn around. But the Scripture says, "No weapon formed against you will prosper" (Isaiah 54:17). God was saying, "Trouble may come, sickness may form, people may do you wrong, but don't worry. It's not going to prosper." That's not how your story ends. God has the final say. He doesn't stop every difficulty, but He promises that it has to go back. It's not permanent.
In Jeremiah 5, God says, "I have placed the sand as the bound of the sea, by a perpetual decree, that it cannot pass beyond it. And though its waves toss to and fro, yet they cannot prevail; though they roar, yet they cannot pass over it." Though the ocean may be a billion times bigger and more powerful than the sand, God put an everlasting ordinance in the sand that it would keep the ocean in its boundaries. The ocean may roar and pound the sand with its waves, but because of God's decree, the sand will not be overpowered.
What you're up against may look bigger, more powerful, but when you have God's Word in your heart, that's the everlasting ordinance. His Word is the decree that enables you to withstand storms that are stronger, overcome enemies that are bigger, and accomplish dreams that seem impossible. Now make sure you do your part and keep God's Word in your heart. For any area that you're struggling in, you need to find Scriptures that you can stand on. It's good to pray, but there's nothing more powerful than saying what God says about you. Even when Jesus was tempted by Satan in the desert, He said, "It is written" (Matthew 4:4). With each temptation, He went back to the Scripture and quoted what God said. When you're in difficult times, don't just say what you feel, what you think, or what you want. Say what God says about your situation.
When the enemy roars at you like the waves roaring at the beach, roar back at him. When the thought roars, "You'll never get over this sickness," roar back, "I will live and not die. The number of my days God will fulfill." When he roars, "You can't accomplish your dreams. You don't have the talent," roar back, "Whatever I touch prospers and succeeds. Goodness and mercy are following me." Don't let him have the last roar. You have God's Word. His promises will prevail. Now tell the ocean to go back.
