1 Corinthians 16:13 Updated American Standard Version (UASV) 13 Be watchful, stand firm in the faith, act like men, be strong. "God calls Christians to a way of life that incites opposition from the world. He calls his people to enter a spiritual war in which opponents seek believers’ destruction and fight against believers’ goals. In this hostile world, it is essential that followers of Christ be courageous and strong." - Richard L. Pratt Jr.
