Covetousness has often moved men to violence that they might not have otherwise been inclined to do. For instance, wicked king Ahab had a strong desire to obtain a vineyard belonging to Naboth (1 Kings 21:1-4). When Naboth refused to sell the vineyard, Ahab returned to his house to mourn. When Jezebel saw her husband’s grief, she created a plan to take the vineyard by force (1 Kings 21:5-16). This principle is not limited to Ahab and Jezebel but has unfortunately been the historical motive for many acts of violence. When men cannot fulfil the lusts of their flesh in a righteous manner, they simply resort to other means which often includes violence.
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).
Discerning the difference between the workings of God and the mischief of Satan sometimes serves as a difficult task for believers. Although the Devil is called the tempter in Matthew 4:3 and 1 Thessalonians 3:5, the Bible also shows that God uses temptation to try a man (Genesis 22:1). Other than the association to instigating temptation, God and Satan have no other common ground in this matter. The Devil’s motive and method of temptation is simply wicked. On the other hand, the Lord tempts only for the sake of trying one’s faith to bring about a righteous outcome. Do not discount the fact that God never tempted anyone with evil (James 1:13).
