Charlie Kirk was one who kept on the ‘straight and narrow’
Revelation 22:11
“Let the one who does wrong, still do wrong; and the one who is filthy, still be filthy; and the one who is righteous, still be righteous; and the one who is holy, still be holy.”
Isaiah 5:20
“Woe to those who call evil good and good evil, who put darkness for light and light for darkness, who put bitter for sweet and sweet for bitter!".
