What does Luke 4:11 mean?

This continues a quote from Scripture, spoken by Satan himself. After Jesus responds to other temptations by citing the Bible, the Devil uses manipulated, out-of-context quotes of the Old Testament. Here, he suggests that if Jesus deliberately jumps from the top of the temple complex (Luke 4:9–10), God's promise means He will be spared.

Of course, none of God's promises come outside the context of His will. The reference cited by Satan (Psalm 91:11–12) doesn't mean God-followers can act carelessly. Jesus will respond as He does all other temptations: He commits to following God's timing, and again references Scripture which truly addresses this situation (Luke 4:12; Deuteronomy 6:16). Jesus won't deny that God would have intervened; He rejects the idea of presuming on God's will.

In rejecting this temptation, Jesus will refuse to "test" God by arrogantly telling Him how He should act. He won't skip the suffering of the cross by prematurely revealing Himself as Messiah to the entire world.
