Are God's promises to His people reliable?

I will bring back the captives of My people Israel; They shall build the waste cities and inhabit them; They shall plant vineyards and drink wine from them; They shall also make gardens and eat fruit from them. 15I will plant them in their land, And no longer shall they be pulled up From the land I have given them," Says the LORD your God. (Amos 9: 14-15) He is the LORD our God; His judgments are in all the earth. 8He remembers His covenant forever, The word which He commanded, for a thousand generations, 9The covenant which He made with Abraham, And His oath to Isaac, 10And confirmed it to Jacob for a statute, To Israel as an everlasting covenant, 11Saying, "To you I will give the land of Canaan As the allotment of your inheritance," (Psalm 105: 7-11) Then the LORD appeared to Abram and said, "To your descendants I will give this land." And there he built an altar to the LORD, who had appeared to him. (Genesis 12: 7) Dwell in this land, and I will be with you and bless you; for to you and your descendants I give all these lands, and I will perform the oath which I swore to Abraham your father. (Genesis 26: 3) And behold, the LORD stood above it and said: "I am the LORD God of Abraham your father and the God of Isaac; the land on which you lie I will give to you and your descendants. (Genesis 28: 13)
