Your actions reveal what is going on in your heart. They reveal what you genuinely feel.
Your words reveal what is going on in your mind. They reveal what you genuinely think.
If those two things are not aligned, then your actions supersede your words.
If you say you love someone and then treat them poorly, you don’t truly love them.
If you say, you don’t depend on a substance, but you cannot make it through the day without it. Then you are addicted.
If you say you are a follower of Jesus and then do not do what he says, you are not a Christian.
In the end, you must be brutally honest with yourself about what your actions are showing the world, no matter how much you protest that you believe something different. A heart for Jesus will lead to doing the things Christ desires for your life.
