The words you speak put spiritual laws in motion.  They either allow the law of sin and death to take over or they activate the law of the Spirit of life in Christ Jesus.  The moment one of those laws is set in motion, unless you do something to stop it, it will continue to function until it accomplishes its end result.

To understand this, let’s look at the natural law of gravity.  We live under its influence all the time.  It’s constantly operating on us and around us.  Because, through the physics of the earth, it’s already been set in motion, it functions automatically, accomplishing its end result which is to hold us to the ground.

When you get in an airplane, however, that hold is broken.  You are free to fly from one point to another, not because the law of gravity ceases to operate, but because the plane introduces another law that supersedes it – something called the “law of lift.”

Spiritual laws work the same way.  The law of sin and death, like gravity, is always at work in the world.  Because of the devil’s influence, it constantly exerts a downward pull toward darkness and the curse.  Apart from Jesus, the effect of that law is inescapable.

However, thank God, as born again believers, we are not set apart from Jesus.  We are in Him and as Romans 8:2 says, the “law of the spirit of life in Christ Jesus has set us free from the law of sin and death.”

Like the law of lift, however, the law of the spirit of life in Christ Jesus doesn’t operate automatically.  It must be activated.  We choose to put it into effect by speaking words of life.  Since “death and life are in the power of the tongue”  (Proverbs 18:21), if we don’t speak life over the different areas and situations in our lives, the laws of death will continue operating there by default.

Many Christians don’t know this, but it’s true.  Even though we are born again and Jesus shed His blood to give us the authority to live His victorious life, as long as we keep talking like the world, we will keep on getting the world’s negative results.

Whosoever keeps his mouth and his tongue, keeps his soul from troubles.  Proverbs 21:23

A man shall eat good by the fruit of his mouth, but the soul of the transgressors shall eat violence. Proverbs 13:2

A fool’s mouth is his destruction, and his lips are the snare of his soul.  Proverbs 18:7
