Beloved, although I was very eager to write to you about our common salvation, I found it necessary to write appealing to you to contend for the faith that was once for all delivered to the saints. For certain people have crept in unnoticed who long ago were designated for this condemnation, ungodly people, who pervert the grace of our God into sensuality and deny our only Master and Lord, Jesus Christ.
To read more on a Christian answer to the problem of evil I particularly recommend John Frame's Apologetics to the Glory of God and Greg Bahnsen's Always Ready. Professor Frame deals with all of these unbiblical theodicies and more and then shows in detail how Scripture gives us a new past, present, and future perspective on evil and promises faith to overcome doubt. Dr. Bahnsen works logically through the syllogism to show that the problem of evil is not a problem for the believer but for the unbeliever and then shows the sin of unbelief in God's goodness. You can find links for both of these books in the Apologetics recommendations below.
