Walter Brueggemann, in his commentary on the binding of Isaac in Genesis 22, offers the following insight into temptation.
In our sophistication, we may find the notion of “testing” primitive. But Christians may take no comfort that this is in the Old Testament. The same issue is clear in the New Testament. Nowhere is it more visible than in the Lord’s prayer. How odd that settled, complacent believers pray regularly, “lead us not into temptation” (Matt. 6:13; Luke 11:4). The prayer commended by Jesus is that God should not put us in a testing situation where we are driven to choose, decide, and risk for our faith. The prayer is the petition that our situation of faith may not be so urgent that we will be found out. The prayer bespeaks fear that we will be found wanting if such testing comes.†
