Note 3 at Mt 4:6: Notice that Satan quoted scriptures in his temptation of Jesus. However, to this passage from Ps 91:11-12, Satan added the phrase "at any time," and he also omitted the phrase "in all thy ways" (Ps 91:11), thereby changing the whole meaning of those scriptures. God's promise was to keep us in all our ways (in context, ways that would keep us dwelling in the secret place of the Most High). His promise was not to deliver us "at any time" and in any situation, even if we were out of God's will.

Satan may appear as an angel of light and even use Scripture to tempt us. He will, however, always twist the Scripture. We can detect this, as Jesus did, by comparing scripture with scripture. There is no substitute for having a thorough understanding of the Word of God. Knowing only a few scriptures can be dangerous.
