The good man brings good things out of the good stored up in his heart, and the evil man brings evil things out of the evil stored up in his heart. For out of the overflow of his heart his mouth speaks.
Someone once said, if you press an apple you get apple juice, if you press the grapes you get grape juice. You can't get grape juice if you press apples. What is stored is what will come out.
What is stored in our heart only will come out. If we store good things, good things will come out. If we store evil things, evil things will come out. (Matthew 7:17-18) Likewise every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit.
To know what is stored in your heart, think about those words that came out of your mouth last one week. Let us store good things.
Is there any unwholesome words from your mouth last week. Please confess to God and apologize to the person who you would have probably hurted with such words.
