I do not pray that You should take them out of the world, but that You should keep them from the evil one. 

Blameless and harmless, children of God without fault in the midst of a crooked and perverse generation, among whom you shine as lights in the world. § You are the salt of the earth … the light of the world. § Let your light so shine before men, that they may see your good works and glorify your Father in heaven.I also withheld you from sinning against Me.The Lord is faithful, who will establish you and guard you from the evil one. § I did not do so, because of the fear of God. § [He] gave Himself for our sins, that He might deliver us from this present evil age, according to the will of our God and Father. § Now to Him who is able to keep you from stumbling, and to present you faultless before the presence of His glory with exceeding joy, to God our Savior, who alone is wise, be glory and majesty, dominion and power, both now and forever. Amen.
