Despite its harshness, God's decision to destroy the earth and humankind by a flood was ultimately an act of great love for His creation. By it, He intervened to derail the degradation of human morality before it became permanently set in man's nature. John Ritenbaugh also explores the first mention of God's grace in Scripture, which occurs within the Flood narrative, showing that the entire episode and the subsequent covenant were effects of His grace.
Martin Collins, reflecting that precious stones are highlighted in Scripture 26 times, focuses on the stones in the New Jerusalem referenced in Revelation 21:9ff The 12 precious stones radiate pure light. When precious stones are the recipients of polarized light, all colors of the rainbow are generated (anisotrophic) or they go pure black (isotrophic). Jewels in Scripture are symbols of permanence. The Creator of the Holy City has abundant resources. Each tribe of Israel has its own gate constructed of a precious gem. Our offerings must reflect the radiance of Christ. Only God can assess the quality of light in the precious stones He has called.
In Matthew Christ likens end-time events to the time of Noah's Flood. John Ritenbaugh gives insight into how this end time flood might manifest itself and what we can do to avoid being swept up in it.
