What does the sixth petition mean?

"And do not bring us to the time of trial, but rescue us from the evil one" means: By ourselves we are too weak to hold our own even for a moment.¹ And our sworn enemies—the devil,² the world,³ and our own flesh⁴—never stop attacking us. And so, Lord, uphold us and make us strong with the strength of your Holy Spirit, so that we may not go down to defeat in this spiritual struggle,⁵ but may firmly resist our enemies until we finally win the complete victory.⁶
