The tongue can corrupt a whole body, depending on what comes out of the mouth.

in Chap. 3, our faith is tested on how we control our tongue

if we cannot control it, we do not have faith

James wants us to understand how lethal the tongue is

Talk with caution. You are carrying a sinful heart.

The guidance of the tongue comes from the spirit within us.

verses 5 and 6 shows us how much damage a tongue can do.

why might an uncontrollable tongue be a sign of lack of faith?

when James uses the term 'cursing', he means the whole category of speaking with guile

Let us be careful to control that tongue.

That spark, which could set fire to a whole forest

Let us seek the LORD, in helping us to do the right thing.
