What kinds of words do you use? How many times a day do you say things like: "Oh my God" or "Jesus Christ!" or simply say, "God..." When I was a child I was told that when we use God's Name we are in effect calling Him to our side as though we were calling someone in the next room.
There are other things we say like "gosh" and "darn" that I have been told are minced oaths. In other words, they are substitutes for swear words or "unwholesome talk."
Let no unwholesome word proceed from your mouth, but only such a word as is good for edification according to the need of the moment, so that it will give grace to those who hear. Ephesians 4:29 (NASB)
But now you also, put them all aside: anger, wrath, malice, slander, and abusive speech from your mouth. Colossians 3:8 (NASB)
Rather than rounding that bush again, I want to simply remind you (and me) that the words from our mouths reveal the spiritual condition of our hearts. So many of our words are careless and reveal that we are angry with God because He is not doing things our way. Other words are spoken with careless abandon, not even thinking of the implications our words can bring.
With our own mouths we condemn ourselves. We murmur and grumble and complain against God because at the root of it all we worship and idolize ourselves. "ME" is the most important person in our world. "ME" must be satisfied, "ME" must be worshiped. We have no regard for what God is doing through the circumstances we are presented with, all we see is that "ME" doesn't like it. So we utter things like "God!!" complete with disgusted tone of voice. We proclaim that God is not fair, does not love us and is not listening to our prayers and petitions. We determine that God simply does not care.
Oh faithless and wicked heart...
I have to come back over and over to the gospel- to the truth. I am a wretch, I am unworthy, and I cannot do anything to affect my position before God. I need Christ. Because I am found in Christ I am obligated by love to worship HIM and not myself. When that change begins - the worship exchange- in my heart where I dethrone myself and begin to view God Most High as Who He is, then my actions and words will begin to get in line with what I believe to be true.
You see, if you really don't believe that God is Most High, you won't speak of Him in worship. Your use of His Name will be flippant and casual. His Name will become a point of emphasis in your speech so people really know how exasperated you are.
If you do see God as Most High your heart will be crushed as you realize what you are revealing about what is going on inside you by your words.
The only response is to repent...repent of the sin that lurks within the heart and dethrone yourself. Restore the rightful King to the throne of your heart. That is how it all begins!
