I'm not sure I agree with this.

I agree with the first part but really question the second part.

James 4:7-8(NKJV)

Therefore submit to God. Resist the devil and he will flee from you. 

Draw near to God and He will draw near to you. Cleanse your hands, you sinners; and purify your hearts, you double-minded. 

I'm 100% on board with this part.  It's the next two verses that I question.

James 4:9-10(NKJV)

Lament and mourn and weep! Let your laughter be turned to mourning and your joy to gloom. 

Humble yourselves in the sight of the Lord, and He will lift you up.

Do you really think we need to go God as sniveling, weak, gloomy and unhappy people in order for Him to lift us up?  Seriously?  How in the world does that demonstrate faith?  In fact it flies directly in the face of one of my foundational verses. 
 

Romans 5:3-5(NKJV)

And not only that, but we also glory in tribulations, knowing that tribulation produces perseverance; 

and perseverance, character; and character, hope. 

Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us.

God's first rule of success is glory in your tribulations (have a great attitude).  How does lamenting and being gloomy even come close to "glorying in our tribulations"?

In addition we have this advice from Paul.

Ephesians 3:11-12(NKJV)

according to the eternal purpose which He accomplished in Christ Jesus our Lord, 

in whom we have boldness and access with confidence through faith in Him. 

 

Again how does lamenting, whining, and being gloomy demonstrate "boldness and confidence" through faith in Christ?

And just to finish off this topic.

2 Timothy 1:7(NKJV)

For God has not given us a spirit of fear, but of power and of love and of a sound mind.

As heirs in Christ I just don't believe that God wants us to be little whiners for Him to help us and that, at least to me, is what James is telling people to do.
