We talk all the time. You've heard people say, "She rambles on constantly", or "What a motor mouth!"
Do we really consider what pours from our mouth? The Bible says our confession (want we say) carries a lot of weight. There is a progression. In Hebrews 3:1, we are instructed to make the right confession. In Hebrews 4:14, we are instructed to “hold fast” our confession. In Hebrews 10:23 we are instructed to hold it fast "without wavering". That means we must keep making the words of our mouth agree with the Word of God.
“Let us hold fast the confession of our hope without wavering” (Hebrews 10:23 NASB). Did you notice the two added words: without wavering?
There are three successive stages. First, we make the confession. Second, having made it, we hold fast to it. We do not change. We can't speak like God is with us one day and act like He isn't the next day. Third, we hold it fast without wavering. Why do you think without wavering is put in there? To me, from personal experience, it implies that when we make the right confession, we are going to encounter negative forces and pressures that will come against us. Even though we have made the right confession, believe the right thing, and we are holding it fast, there may come a time when the pressure increases. There may be times when it seems that all the forces and powers of darkness are turned loose against us, tempting us to let go of our confession.
Our job at this point is to NOT let go!
This is where Paul encourages us: “Don’t let go. Hold fast ... without wavering.” The darker the situation looks; the greater the problem appears; the more the pressure you're experiencing ... the more important it becomes for us to hold on without wavering.
Why is that so important? Because “He who promised is faithful” (Hebrews 10:23 NKJ). Even when we don't understand what's going on, that God is ignoring us ... We must hold to our confession and we'll see "He who promised, IS FAITHFUL"
Whether we see Him or not, whether we understand why things are like they are or not, He is faithful. If we hold fast our confession without wavering, He will do His job. He will be our protector, our provider, our Redeemer. He is faithful. Confess. Hold fast. Don't waver. Here's a tip: when you feel yourself begin to waver (and you will), just hold on tighter to the promises in the Bible! That's your strength!
We can use our words to increase or decrease. Words are not just air rolling over our tongue. They mean something. "Life and death", the Bible says, "are in the power of the tongue."
