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).
Carnal Christians and those who do not know the Lord consider judging others as the greatest of sins. The opposite actually holds true. Believers fail when they refuse to judge “righteous judgment.” So often, men judge people and situations simply by what is seen or through an emotional response. Yet, this is completely contrary to the scriptural admonition to judge. Instead, we are to “judge righteous judgment.” How can this be consistently done? First and foremost, we need a righteous standard by which to compare all things. In John 12:48, we learn of that righteous standard when the Lord Jesus said that His words would judge men. The Bible is a perfect Book containing perfect laws and offers a perfect standard for making judgments. Therefore, all judgment should be based upon the infallible standards provided by God within His glorious word. We will never go wrong with judging according to God’s perfect standard.
