Blessings and punishments

Leviticus 26:1-20
Consequences of two ways, one is follow God's decrees and are careful to obey his commands, another is not listen God and you reject God's decrees and abhor his laws and fail to carry out all  his commands.
Blessings and punishments:
The reward of obedience is pictured as an idyll of peace and plenty. Best of all, God will walk amongst his people, as he walked in the garden with the first man and woman. This is Eden restored.
Disobedience, on the other hand, will bring calamity on the nation: fatal disease, famine, wild beasts ravaging the land, and war leading to exile.
Why?
There is two ways let us choose, one is blessing another is punishment. The consequence is our choice.
How?
No doubt I chose to follow God's decrees and careful to obey his commands. I needs the blessing from the Lord
