According to Matthew, Jesus spoke these words after the second
temptation. Jesus was quoting Deuteronomy 6:16. Luke 4:12 is a synoptic gospel
parallel. A similar passage is Isaiah 7:12 which occurs two verses before one
of the most famous Messianic prophecies in the Old Testament.
Isaiah 7:12 But Ahaz said, "I will not ask, and I will not put the
LORD to the test." 13 And he said, "Hear then, O house of David! Is
it too little for you to weary men, that you weary my God also? 14 Therefore
the Lord himself will give you a sign. Behold, a young woman shall conceive and
bear a son, and shall call his name Immanuel.
Jesus didn’t need a sign that God loved Him, Jesus was the sign that God
loved the world.
