The one true God does not lie and does not require lying. He is a just God who allows freedom of choice, whether the choice is good or bad. God does not violate freedom of conscience, the god of Islam does. They are not the same.
Believers are sinners—through belief they recognize this.
They understand that the only way to God—who is not simply pure but purity itself—is to first recognize not that they are “precious” but that they are sinners. Broken, flawed, sinful, hopeless. But God has provided the solution—redemption through repentance and faith.
Islam doesn’t REQUIRE lying either. Only forgives it under certain circumstances (like self-preservation). Here is an interesting take by Relevant magazine that gives two examples in the Old Testament of the same sort of forgiveness by God for lying in the same sort of circumstances: http://www.relevantmagazine.com/god/deeper-walk/features/21429-is-lying-ever-okay
