Titus 1:16 They claim to know God, but by their actions they deny him. They are detestable, disobedient and unfit for doing anything good.
Windbag: a talkative person who communicates nothing of substance or interest. In other words, there are a lot of words coming out of the mouth, but the words have no significance. It’s just talk, meaningless chatter. Nobody like a talker who talks with no substance. You know those people who seem to like to hear themselves talk? The ones who are enamored with the sound of their own voice? Worse than just talking, however, is talk without any action to back it up.
For example, politicians who make grand speeches and don’t deliver on promises. Or athletes who tout a forthcoming victory and then play the game like they’ve spent the last 20 years sitting on a couch. Talk is cheap. But action is a precious commodity. We all wish there was more of it in this world. There seems to be plenty of demand but a shortage of supply.
Here’s the thing: God’s not fond of Christian windbags. He doesn’t get real excited about people who claim to know him, but deny him with their lives. In fact Paul writes that these windbags are unfit for doing anything good. You see, when your life doesn’t match your spoken beliefs, you undo your message. You become unbelievable; you can’t be taken seriously… you are a windbag. Because the world is watching to see if you really believe what you believe. They are waiting to see if it makes it past your lips, into your heart, and out of your hands. We are called to be a people of action. So no more wind bagging please. Line up your whole life with who you say He is!
