You can say that you're a Christian all day long. You can say that, no one can look in your heart of hearts and judge you. And you can say that, in your heart of hearts, that you really know that you believe. But all of it is just wash. Do you know what your heart is? It's the very center of your being... the core of your person. Now you're going to tell me that Jesus Christ has the entire center and core of your being, but it doesn't affect the way you walk, talk, or think? no... To receive Him, is to take Him as Savior and Lord. To stand upon Him. This is a mark that the Holy Spirit has truly regenerated your heart... and that you really do belong to Him.
