"O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh." Matthew 12:34
The scriptures tell us that we should love the Lord with all our heart. How do we know whether we do or not? How do we know what has our heart? How do we know what consumes our heart? One way is by examining our lives to see if we are obeying His commandments and doing our best to keep them, walking in them and letting them be the governing factor of our lives. Because if we love Him we will keep His commandments.
Another way to know is by listening to yourself when you talk. What comes out of your mouth? Our verse above tells us that whatever our heart is full of is what will come out of our mouth. If you are full of love for God it will come- you will hear it in the things that you say. If you are full of bitterness, envy, hurt, it too will come out in your conversation. It is so easy to tell where people are just by listening to what they are saying. Like wise, it is just as easy to know where we are by what we are saying. This means that if you aren't sure what is filling your heart, all you have to do is listen to yourself for a while and you will soon discover what it is.
I know people who all they talk about is money- getting their next dollar, how to keep what money they have. I know others that talk about nothing but their ex-spouse and what wrong they did to them. There are those also who talk about their illnesses, aches and pains all the time. And the list goes on. Don't misunderstand me, it is not wrong to talk about these things I have mentioned, but when it becomes your whole conversation and the only thing you talk about all the time, then it means this is what has your heart.
By listening to yourself you will get a pretty good idea of what really has your whole heart.
Have a great day. If you really want to know what is in your heart... just listen to what you are saying.
