Hebrews 4:12
For God's Message is full of life and power, and is keener than the sharpest two-edged sword. It pierces even to the severance of soul from spirit, and penetrates between the joints and the marrow, and it can discern the secret thoughts and purposes of the heart.
Jude 1:15-16
and to convict all the ungodly of all the ungodly deeds which in their ungodliness they have committed, and of all the hard words which they, ungodly sinners as they are, have spoken against Him."
Revelation 2:23
Her children too shall surely die; and all the Churches shall come to know that I am He who searches into men's inmost thoughts; and to each of you I will give a requital which shall be in accordance with what your conduct has been.
