Revelation 14:5

And in their mouth was found no deceit, for they are without fault before the throne of God.

·        Their hearts were right with God, and they were freely pardoned in Christ (MH)

·        Greek, "blameless": in respect to the sincerity of their fidelity to Him. Not absolutely, and in themselves blameless; but regarded as such on the ground of His righteousness in whom alone they trusted, and whom they faithfully served by His Spirit in them. (JFB)

Psalm 32:2 Blessed is the man to whom the LORD does not impute iniquity, and in whose spirit there is no deceit.

Zephaniah 3:13  The remnant of Israel shall do no unrighteousness and speak no lies, nor shall a deceitful tongue be found in their mouth; for they shall feed their flocks and lie down, and no one shall make them afraid.
