Deuteronomy 6:11
And houses full of all good things, which thou filledst not, and wells digged, which thou diggedst not, vineyards and olive trees, which thou plantedst not; when thou shalt have eaten and be full; And houses full of all good things, which thou filledst not, and wells digged, which thou diggedst not, vineyards and olive trees, which thou plantedst not; when thou shalt have eaten and be full;
Deuteronomy 4 through 8 set forth what God required of His ancient people that they might be a holy people to Himself, and those chapters are to be studied and read with profit now because the day of God's great final review is near when the people of this world must stand before the Judge of all the earth to answer for their deeds, since the present is the time of investigation when every character will have been investigated and every case decided for eternity. The verse describes the Lord bringing Israel into the promised land of Canaan to possess and enjoy in abundance what they had not built, filled, dug, or planted. There He would give them great and goodly cities which they did not build, houses full of all good things which they did not fill, wells which they did not dig, and vineyards and olive trees and groves which they did not plant, so that they would eat and be full.
This giving was in fulfillment of His oath to Abraham, to Isaac, and to Jacob to bring them into that land. When they had eaten and were full and satisfied with this prosperity and comfort, they were to beware lest fullness lead them to forget the Lord who gave the blessings, who had brought them out of Egypt from the house of bondage and rescued them from slavery, and to forget His covenant; prosperity is thus placed alongside the warning to remember God and remain faithful to Him. Instead of forgetting, they were to fear the Lord with godly fear, not servile fear, and to serve Him alone, swear by His name, diligently keep His commandments, testimonies, and statutes, and do what is right and good. They were not to go after other gods and the gods around them and not to tempt the Lord as at Massah, because He is a jealous God and a consuming fire who would destroy them for doing evil in His sight.
Obedience would bring well-being, long life, health, happiness, and preservation alive, while doing evil would cause them to soon utterly perish from off the land beyond Jordan which they went to possess. The whole chapter is a lesson for later generations, with parents to teach these words diligently to children in the house and by the way. Merely knowing about Canaan or singing about it was not enough to possess its blessings; the Israelites had to enter and occupy the land, meet its conditions, trust God's promises, and obey His instruction, since the land was theirs on condition of obedience to the law of God.
The same provision is found in taking up responsibilities for God's work, including at Loma Linda and other places, where existing buildings, furnishings, conveniences, and other good things not provided or produced by those entering are seen as blessings provided through God's leading.
