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).
The context of today’s passage confirms that it involves the temptation to do evil. This shows that the author of the temptation is not God, nor can it ever be Him in this context. The death of the one being tempted is the end result. This is why it is so very important for every believer to achieve a scriptural understanding of the source of his temptation. According to James 1:14, “every man is tempted, when he is drawn away of his own lust, and enticed.” The first step of any temptation is a drawing away. If a man refuses to be drawn away, he simply cannot be tempted to do wrong. If a man allows himself to be drawn away, the Devil’s next step involves enticement. It is often at this point that the Devil captures his prey leading him into sin.
Our passage tells us that God is not in all the thoughts of the wicked (Psalm 10:4). It also points out that the thoughts of the wicked “are thoughts of iniquity” (Isaiah 59:7). Obviously, the wicked despise the Lord in their thoughts, but the Lord also despises the thoughts of the wicked. This is why we are told that “The thoughts of the wicked are an abomination to the LORD” (Proverbs 15:26). King David, whom God called “a man after mine own heart” (Acts 13:22), added that the thoughts of the wicked were against him for evil (Psalm 56:5). These wicked thoughts are based upon pride (Psalm 10:4). Conversely, a man yielded to the Lord desires to bring “into captivity every thought to the obedience of Christ” (2 Corinthians 10:5).
