Men tend to fret over the motives behind others’ actions. Instead, men should trust the Lord to deal with the motives at the judgment seat of Christ.
The world is driven by self-preservation and self-promotion. Individually, the natural man is guided by self-serving motives. This should not be true of saints.
One must choose his reward for actions taken. Would he rather receive eternal reward from God the Father, or temporary praise and recognition from his peers?
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).
