God didn't wait for Satan to come to him. He went to Satan.
Yes, oh course ... this wasn't the question.
What was the purpose of this meeting between Jesus and Satan ?
Luk 4:17-21 "And the book of the prophet Isaiah was handed to Him. And He opened the book and found the place where it was written, "THE SPIRIT OF THE LORD IS UPON ME, BECAUSE HE ANOINTED ME TO PREACH THE GOSPEL TO THE POOR. HE HAS SENT ME TO PROCLAIM RELEASE TO THE CAPTIVES, AND RECOVERY OF SIGHT TO THE BLIND, TO SET FREE THOSE WHO ARE OPPRESSED, TO PROCLAIM THE FAVORABLE YEAR OF THE LORD." And He closed the book, gave it back to the attendant and sat down; and the eyes of all in the synagogue were fixed on Him. And He began to say to them, "Today this Scripture has been fulfilled in your hearing."
Our Lord Jesus wanted to experience the temptations of man Himself before He preached to others. In other words, He practiced what He preached.
