"There was never an angry man that thought his anger unjust" - Francis de Sales
Trials squeeze us like a sponge and we do not notice all the gunk that comes out: the blame, anger and bitter speech. We excuse our bitter words as just and our anger as deserving. James links the very anger and bitter speech we justify in trial as being the opposite of being doers of God's words - v.22. This is because we cannot " receive with meekness the implanted word" - v.21. When one cannot receive the word of God, one cannot receive God - nor can they work for the Kingdom. Grumbling in service toward others, blaming others in self-righteousness and a quick temper must be seen as God sees it - "filthiness and rampant wickedness" (v.21). This means that encouragement, exhortation and even correction are lost to you and you will turn to broken cisterns for water.
"It is not what goes into the mouth that defiles a person, but what comes out of the mouth; this defiles a person.” - Matthew 15:11.
There is only but one way please God and walk in God's Presence - stop justifying self-righteous anger and defile oneself of bitter speech. When you are squeezed by your husband, wife, parents, children, friends - mind what you allow to pour into your mind and comes out of your mouth? Do you justify your anger and bitter words? If so, you are likely talking yourself out of God's Presence and becoming disabled to the word of God. The good news is that we can also talk our way back to God through heart-felt repentance and humble confession - soak in the clean water of God and replace the "filthiness" that is generated by the flesh. In doing so, we gain our hope - we gain Christ!
