Fruits of the Spirit

I am wondering why Christians have problems exercising the 'fruits of the Spirit' in everyday life. Though we spend a great deal of time in church and learning about Christ, it seems as though Christians often have difficulty showing "love, joy, peace, longsuffering, gentleness, goodness, faith, meekness,and temperance" when faced with difficulties.

Why is the divorce rate for Christians higher than that of non-Christians? Though over a decade has passed, a 1999 study revealed:

"While it may be alarming to discover that born again Christians are more likely than others to experience a divorce, that pattern has been in place for quite some time. Even more disturbing, perhaps, is that when those individuals experience a divorce many of them feel their community of faith provides rejection rather than support and healing. But the research also raises questions regarding the effectiveness of how churches minister to families. The ultimate responsibility for a marriage belongs to the husband and wife, but the high incidence of divorce within the Christian community challenges the idea that churches provide truly practical and life-changing support for marriages."

A 2008 study was no more encouraging when it stated that:

After months of revived debate over divorce and its increasing acceptance among Americans, a new study affirmed born again Christians are just as likely as the average American couple to divorce.

The Barna Group found in its latest study that born again Christians who are not evangelical were indistinguishable from the national average on the matter of divorce with 33 percent having married and divorced at least once. Among all born again Christians, which includes evangelicals, the divorce figure is 32 percent, which is statistically identical to the 33 percent figure among non-born again adults, the research group noted.

What are we doing wrong? Why are we no better than the world in spite of our prayers, scriptural knowledge, and relationship with God? Why is the enemy allowed to break up Christian marriages? Is it the work of the enemy or the Matthew 19:8 hardness of our hearts ( which returns me to the original question regarding not demonstrating the 'fruits of the spirit' to one another)? Is this a sign of the Romans 1:26 unnatural affections in the end times? If we do not exercise the fruits of the Spirit to one another, we have already begun to fulfill the end-time scriptures (Mark 13:4-31) and must be vigilant of the second coming of Christ.

Take ye heed, watch and pray: for ye know not when the time is. (Mark 13:33)
