Does being disrespected make you angry?  Is that anger justified?  Certainly if anyone should have been accorded respect, it would be the Lord of Glory.  His anger would certainly have been justified.

Let this mind be in you, which was also in Christ Jesus: Who, being in the form of God, thought it not robbery to be equal with God: But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.  Philippians 2:5-8

The tiny word let implies yielding and/or submitting to the truth (thy word is truth).  Only genuine believers can do this.

Can a man by taking thought add to his stature?  Can a leopard change his spots?  Not at all! But with God, nothing is impossible.  Having the mind of Christ is a supernatural enablement which is the result of regeneration (being born again) and sanctification [letting the word of Christ dwell (take up its life) in you richly].

For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.  I Thessalonians 2:13

For who hath known the mind of the Lord, that he may instruct him? But we (born again ones) have the mind of Christ. I Corinthians 2:16

So, do you need to have respect in order to be effective?  If not, why are you angry?

…let the word of Christ dwell (take up its life) in you richly…
