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).
The Bible always serves as the best source for adequately defining a Bible word. According to Joshua 7:19, confession is connected to the act of telling what a person has done—refusing to keep it hidden. Joshua told Achan to give “glory to the LORD God of Israel, and make confession unto him; and tell me now what thou hast done; hide it not from me.” Psalm 32:5 identifies confession as acknowledging a matter—refusing to hide it. Additionally, Proverbs 28:13 defines confession as the opposite of covering one's sin. In John 1:20, the word confessed appears twice with a defining phrase in between— “and denied not.” In the same manner, Acts 19:18 demonstrates that those who “confessed” “came . . . and shewed their deeds.” The scriptural evidence points to confession as the willingness to make known that which could otherwise be private, personal, or hidden. Keep in mind that regardless of one's willingness to confess, nothing can be hidden from the Lord.
