In the sixth petition (which is, And lead us not into temptation, but deliver us from evil)1 we pray, that God would either keep us from being tempted to sin,2 or support and deliver us when we are tempted.3
13 And lead us not into temptation, but deliver us from evil: For thine is the kingdom, and the power, and the glory, for ever. Amen.

2 Corinthians 12:7-8
7 And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure.
8 For this thing I besought the Lord thrice, that it might depart from me.
