The average believer would never consider the word joy to be an appropriate descriptive term for temptations. There is a great explanation for this as the average believer experiences little to no victory when tempted. Temptations put a man’s faith on trial. When his faith stands the test, he learns patience. Therefore, he sees temptation as a means by which he can grow in the Lord and add virtues such as patience. It is not that he finds joy in the temptation itself, but that God can and will use that temptation to make him "perfect and entire, wanting nothing" (James 1:4). Believers who fight through and obtain victory find joy in knowing that their faith pleases God (Hebrews 11:6).
It is easy to tell others what to do and how to do it, but very unwise to fail to follow one’s own instructions and teachings. In fact, man naturally seems to want to place greater burdens upon others than he himself is willing to bear. This was one of the primary issues addressed by those attending the council of Acts chapter 15 in Jerusalem. Peter concluded with the other apostles in agreement that it was not right to ask others to bear a yoke that previous generations were unable to bear (Acts 15:10). This does not mean that believers change their teaching to fit their obedience. Rather, believers ought to obey the truth and teach these truths to others. How many preachers and teachers have spoken about subject matters only to refuse to obey the very truths they have taught to others?
