Note 2 at Mt. 4:3: Two of Satan's temptations began with, "If thou be the Son of God." Jesus was God incarnate (1 Tim. 3:16), but He humbled Himself and took upon Himself the form of a servant and became a man (Phil. 2:6-8). This human part of Jesus was capable of doubting who He was or the tempter would not have used this approach. To think that Satan was expressing his own doubts would downgrade this whole confrontation to such a degree that these temptations would lose their validity. Hebrews 4:15 reveals that Jesus "was in all points tempted like as we are, yet without sin." Surely one of Satan's strongest temptations, as exhibited by the fact that he used it on Jesus, is to try to cast doubt on the most basic of beliefs: who we are in Christ, and what our call is.
