FRESH FAITH, FRESH GOSPEL
The dictionary defines "fresh" as that which is newly made or obtained; that which does retain the original properties without any degradation. Conversely, "staleness" is defined as: having lost the freshness, effervescence, or palatability; lacking originality or spontaneity; impaired in efficacy, vigor, or spirit, as from inactivity or boredom; having lost effectiveness or force through lack of exercise or action.
Spiritually speaking, a fresh faith is that which is active, alive, and meaningful today. It has a sense of newness, recentness, not yesterday and not tomorrow. Presentness: a moment or period in time perceptible as intermediate between past and future: now. Therefore a fresh gospel means a fresh faith and as a stale gospel means a stale faith.
