I am not asking that You take them out of the world, but that You keep them from the evil one. — John 17:15

Jesus doesn't pray that you'd be taken out of the world, but kept from the evil one. You're left in the world on purpose—to be salt and light, so they may see your good works and glorify your Father. The Lord is faithful and will guard you from the evil one. He's able to keep you from stumbling and present you blameless with great joy.
