"So we may boldly say: 'The LORD is my helper; I will not fear. What can man do to me?' "
Because God is with His churchmen; and because God will never forsake them; and because He is sufficient to meet all our needs (so that we need not covet what others have)--we may make the statement (above), and exude that kind of confidence.
Bold living is not the result of possessing the things of the world (as so many wrongly imagine). Instead, valorous conduct comes about because the God who created the world, and saves His own, is cherished in the heart.
[Puritan quote of the day: "Prayer crowns God with the honor and glory that is due to His name; and God crowns prayer with assurance and comfort." --Thomas Brooks, in "Heaven on Earth"]
