As confirmed by this clip from The Colbert Report , arms manufacturer Trijicon inscribes citations to New Testament verses on gun sights it provides to the Marine Corps and Army.
As one example, Trijicon has inscribed 2COR4:6 on some of its sights, which is a reference to Second Corinthians and a verse that exults over the glory of God as reflected in the face of Jesus Christ.
Seems as though Jesus can not only guide us along a straight and narrow path, but bullets too. Ready, aim, pray, fire.
Forgetting church-state issues, is the use of New Testament verses on gun sights unseemly? Not really. Remember Jesus, according to one verse, came not to bring peace, but a sword (Matthew 10:34). Trijicon just makes clear that he came to bring hot lead also.
