As the terebinth and oak leave stumps when they are cut down, so the holy seed
will be the stump in the land. (Isaiah 6:13)
The Bible gives to us the all-encompassing, central term of the covenant "Remnant" (stump), whose meaning includes "the future generations," "those left behind" to take responsiblity for the future of the age and the nation and the "scattered ones."
When God's people, the Israelites, faced fearsome disaster and destruction due to their sin and idol worship, God remembered the promise He made to their ancestors and left behind people of the covenant.
It was through these very people that were "left behind" that Israel was brought to restoration, and this is the Remnant Ideology, subsequently leading all the way to Christ that flows throughout the Bible.
In this present day which is covered in idols, religion, and the culture of darkness,
God will raise up the Remnants, who have the Gospel, as the watchmen of the 21st century, and restore this age.
