When somebody calls you something, either good or bad, that seed is planted in your soil. Now you get to determine whether or not that seed takes rot and grows. When you dwell on what was said, you are watering the seed. You're giving it a right to become a reality. That's why it's so important that we're disciplined in our thought life. It's great when people tell you, "You're Blessed. You're talented. You're going to do great things." Water those seeds. Meditate on those throughout the day. That's what you want to become a reality.
This is what the Lord told Joshua after Moses had died and he was to lead the Israelites into the Promised Land: "If you will meditate on what God says about you day and night, you will have good success and prosper in everything you do." When your mind is filled with thoughts of faith, thoughts of hope, and thoughts of victory, that's what will become a reality.
Do you know why that man who was in his forties was still struggling? He let those derogatory comments play over and over in his mind. Every time he thought about it, He was watering that seed year after year. It's sad to say, but it became a reality. How different would his life be if he had just learned to hit the delete button? Instead of constantly playing the negative, he should have gone around thinking,
I'm a masterpieces. I'm one of a kind. I'm talented. I've got seeds of greatness. It would have been a whole different story.
