Lately I've been learning to use the voice activation function on my phone. It's amazing that with a simple command of my voice, my phone does what I tell it to do (sometimes!).
In a similar way, your destiny is voice activated. What I mean is, believe it or not, your life is a product of the words you speak.
Look at Numbers 14:1-9. All the Israelites grumbled against Moses and Aaron and said, "If only we had died in Egypt! Or in this wilderness!" (v2) Guess what? That's exactly what happened. Those Israelites who grumbled against Moses and Aaron (and against God and His plan) died in the wilderness. Their words determined their destiny.
Compare that to the words of Joshua and Caleb (who actually explored the land that everyone was talking about!) . Instead of speaking words of fear, they spoke words of faith. They said, "If the Lord is pleased with us, He will lead us into that land, a land flowing with milk and honey, and will give it to us." (v8) And that's exactly what happened. Joshua and Caleb were the only ones of their generation to enter the Promised Land (Numbers 14:30). Joshua and Caleb's words determined their destiny.
What can we learn from this? You create your life by the words you speak.
Why do you think God created the universe with His words, starting with "Let there be light"? I believe in part it was to show us that your words have creative power. Put another way: our words create our worlds.
Question: What are you saying these days about your life? What are you saying about your family, your health, your workplace, your church, your future?
If you keep speaking fearful, worrisome, negative, and complaining words about your life ("I'm going to fail!" "My life sucks" "I hate my life"), your life will be exactly that, like a self-fulfilling prophecy.
But if like Joshua and Caleb you speak words of faith based on God's Word ("I can do all things through Christ who strengthens me" "This problem is big, but my God is bigger" "I am abundantly blessed" and "God's grace is sufficient for me"), you'll find that those words will affect the way you think, feel and live, and lead the way for your destiny.
It's no wonder James 2 says that your tongue is like a rudder on a ship; it's so small but it determines the direction of your life.
If you will watch your words and recognize that your destiny is activated by what you say, like Caleb and Joshua by God's grace you can speak your way into God's Promised Land for you.
