'Unblemished' in the Bible

according as He did choose us in him before the foundation of the world, for our being holy and unblemished before Him, in love,

that he might present it to himself the assembly in glory, not having spot or wrinkle, or any of such things, but that it may be holy and unblemished;

that ye may become blameless and harmless, children of God, unblemished in the midst of a generation crooked and perverse, among whom ye do appear as luminaries in the world,

in the body of his flesh through the death, to present you holy, and unblemished, and unblameable before himself,

how much more shall the blood of the Christ (who through the age-during Spirit did offer himself unblemished to God) purify your conscience from dead works to serve the living God?

but with precious blood, as of a lamb unblemished and unspotted -- Christ's --

And to Him who is able to guard you not stumbling, and to set you in the presence of His glory unblemished, in gladness,

and in their mouth there was not found guile, for unblemished are they before the throne of God.
