There is not ambiguous place on the way of serving the Lord

Deuteronomy 28:45-68
If you don't obey the Lord your God, all these curse will come upon you. They will be a sign and a wonder to you ad your descendants forever.
Serve the Lord joyfully and gladly in the time of prosperity  verse to Serve the enemies in hunger and thirst, in nakedness and dire poverty.
The Lord will bring a nation against you from far away from the ends of the earth like an eagle swooping down.
Because of the suffering that your enemy will inflict on you during the siege you will eat the fruit of the womb, the flesh of the sons and daughters.
If you do not carefully follow all the words of this law which are written in this book, and do not reverse this glorious and awesome name- the Lord your God- the Lord will send fearful plagues on you and your descendants.
All the Lord said has happened on Israelite a hundred years later, it shows His word is never failed in this book.
Why?
The Lord said these words and warning messages before it take place, indicated that these are the consequences of the sin of our own and it is allowed by the Lord. The Israelite will know these were the punishment from the Lord.
All of the words in this book are proved be truth in past 2011 history.
How?
Carefully read and obey the commands of the Lord is the best choice. There is not ambiguous place on the road of serving the Lord.
May the blessing of the Lord come upon me.
