What comes out of our mouth is a reflection of what is in our heart. In Ephesians chapter 5 verses 3 through 5, Paul explains this in detail. He talks through the fact that silliness, coarse jesting, filthiness, and immorality are never things that characterize the speech or conduct of someone who claims Jesus Christ is Lord. Everything we say and do, if we truly have Jesus at the center of our life, should be reflection of the characteristics of Jesus Christ.
How would our words define us? Would we be embarrassed or offended for our preacher, our mother, or anyone else to overhear what we say on a regular basis? Regardless of where we are or who we are with, Jesus always hears what we say. Are we living today speaking and acting in such a way that brings glory to God? If not, we need to question where our focus and commitment truly lies.
