It is written:
“So the LORD gave to Israel all the land of which He had sworn to give to their fathers, and they took possession of it and dwelt in it.” (Joshua 21:43)
“Not a word failed of any good thing which the LORD had spoken to the house of Israel. All came to pass.” (Joshua 21:45)
The Bible teaches that God fulfilled HIs promises to Abraham and Moses and all the fathers of Israel in giving to them the land which He had promised.
Nevertheless, many modern day premillennialists teach that God did not fulfill His promises.
“The land promised to Abraham and his descendants was described with clear geographical boundaries….The strange thing is, Israel has never, in its long history, occupied anywhere near this much land—not even at the height of its glory days under David and Solomon….Others claim these promises were conditional and were forfeited by Israel’s disobedience.” (Dr. David Jeremiah, The Book Of Signs: 31 Undeniable Prophecies Of The Apocalypse, 7-8 (Kindle Edition); Nashville, TN: W Publishing)
Despite the claims of premillennialism, God teaches in His Word that He fulfilled the land promises made to Abraham and his descendants.
Furthermore, the inspired Prophet Joshua clearly told the people of Israel that their continued reception of that land was dependent upon their faithfulness to HIm.
“Behold, this day I am going the way of all the earth. And you know in all your hearts and in all your souls that not one thing has failed of all the good things which the LORD your God spoke concerning you. All have come to pass for you; not one word of them has failed. 15 Therefore it shall come to pass, that as all the good things have come upon you which the LORD your God promised you, so the LORD will bring upon you all harmful things, until He has destroyed you from this good land which the LORD your God has given you. 16 When you have transgressed the covenant of the LORD your God, which He commanded you, and have gone and served other gods, and bowed down to them, then the anger of the LORD will burn against you, and you shall perish quickly from the good land which He has given you.” (Joshua 23:14-16)
Premillennialism-like all the systematic teachings of uninspired man-is thoroughly unraveled by the Word of God Almighty.
