Proverbs 28:1 … The wicked flee when no man pursueth: but the righteous are bold as a lion.
2 Corinthians 3:12 … Seeing then that we have such hope, we use great plainness of speech:
Acts 4:31 … And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness. ♥
