" . . . Then the Lord knows how to deliver the godly out of temptations . . . "
Peter establishes this truth (above) on the basis of God's willingness and ability to punish sin (and evildoers). But whereas the Lord did not have a means of redemption for the fallen angels--He *does* provide it to His elect churchmen. On top of that, God delivers them "out of temptations."
What kinds of temptations will you face today? Not all of them will be to do some gross, crass evil. You may be tempted to doubt the love of God, (or even His very existence). You may be tempted to succumb to great discouragement of heart. You may be tempted to quit church, and prayer. The Lord can and will supply His children persevering grace, to withstand and overcome all of these (and more).
