“I will give you all of this if you fall down and worship me.”
This is the third and final stage of the devil’s temptation of Jesus. Daniel Wallace explains the use of “worship” here:
“Here, the tempter attempts to tempt Jesus to worship him. But by the evangelist’s use of the dative direct object, the devil is not asking for mere homage, but for a confession that he is God.” (emphasis mine)
When Satan tempts, he offers what is not his to give in exchange for what is not his to request.
While few of us would knowingly worship Satan, we are much more susceptible when we are tempted with self-worship. Though sin is nothing less than self-worship, it is ultimately submission to Satan’s will. We may worship God on Sunday, but who are we worshiping the rest of the week?
