God never tempts us, nor does He mount a “sting operation” to catch us, just waiting to condemn our every lapse.
Although the English translation of this petition could be misunderstood, the underlying Greek text actually means “do not allow us to enter into temptation” and “do not let us yield to temptation” (Catechism paragraph 2846).
Far from trying to trip us up, God so ardently wants to free us from sin that He became man to save us from its thrall. Christ, Who Himself conquered temptation in His earthly life, teaches us that we can only resist through vigilant prayer in union with Him.
By asking God for help in our struggles to live a moral life, we recognize our weakness and frailty, our tendency to give in to sin. Such humility, grounded in the truth about ourselves, draws down God’s grace upon us – the very grace that He is eager to give us, if we just open our hearts to receive it.
With the light of the Holy Spirit, we can see temptation for what it truly is: evil masquerading as something good. But however attractive a temptation may be on the surface, we know that it’s an illusion, for sin ultimately hurts us.
