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).
It is much easier to serve God together with others rather than alone. There is great wisdom attained through the right kind of fellowship with other like-minded believers. When one believer wavers during times of temptation, his “fellow” believers will encourage him to stay faithful to the Lord’s work. When one of the saints struggles in times of uncertainty, his fellow believers can remind him of God’s faithfulness. The Bible shows us that the early church thrived in the Lord’s work. Those early Christians served the Lord with a great zeal. The secret to their success most definitely included their continuation in fellowship and incorporating some basic principles. For instance, the Lord Jesus sent out His disciples by twos (Mark 6:7) and the early church followed suit (Acts 13:2). God has given us a great insight into the importance of fellowship by emphasizing it so frequently.
