Moses told Israel to keep the commandments of God, and here is why,
“For the LORD your God is bringing you into a good land…” (Deuteronomy 8:7-9).
Then he pictured the goodness of the land. After that, Moses reminded them of something else they were to do, “When you have eaten and are full, then you shall bless the LORD your God for the good land which He has given you” (Deuteronomy 8:10).
Israel, obey God because of the good land He is giving you. Israel, bless God because of the good land He has given you.
Church, obey God because He had given you every spiritual blessing in the heavenly places in Christ. Church, bless God because of the good home that awaits you upon leaving this earth.
