Today I read an article by Christianity Today titled A History of Darkness. It describes a condition that Christians have often experienced throughout history that has come to be known as The Dark Night of the Soul. 

If you are a genuine believer, one who has accepted the Lord Jesus Christ and repented of your sins, I'd encourage you to read the article. You might at some point in your life encounter this condition. But be sure that your separation from God is not your own doing through sin or withdrawal from God. For there are 4 reasons God might seem far from us. 1) We do not have a genuine relationship with him 2) We have unconfessed sin in our lives 3) We've walked away from God, which I suppose is a form of sin 4) He has withdrawn the feeling of His presence so that we will come to a truer understanding of who He actually is. 

Here is the article. http://www.christianitytoday.com/le/2011/fall/historydarkness.html
