We reap what we sow: the law of the harvest

There are many references in the Bible about the law of the harvest: "For whatsoever a man soweth, that shall he also reap", Galatians 6:7.

This is a universal law of learning, balance and returning. This rule is the balance of the Golden rule: "Do unto others as you would have them do to you", Matthew 7:12. The Golden Rule is a law of reciprocity that points us to the Good and the correct. When this rule is violated, acts the law of the harvest with curses.
The universe gives us back what we give. If we are progressive, precise and exact, we improve life ("I am the way, the truth and the life", John 14:6) that is we live the spiritual gifts we reap blessings as it is explained in Galatians 6:7-8: "Do not be deceived: God cannot be mocked. A man reaps what he sows. Whoever sows to please their flesh, from the flesh will reap destruction; whoever sows to please the Spirit, from the Spirit will reap eternal life"
If not, if we sow sin and error we reap curses. That is why in the gospel of Luke in the Sermon of the Mount we have 4 blessings and 4 curses:
The four blessings are:
"Blessed are you who are poor, for yours in the kingdom of God"
"Blessed are you who hunger now, for you shall be satisfied"
"Blessed are you who weep now, for you shall laugh"
"Blessed are you when men hate you, and ostracize you, and insult you, and scorn your name as evil, for the sake of the son of man" Luke 6:20-22
The four curses are:
"Woe to you who are rich, for you have already received your confort"
"Woe to you who are well fed now, for you will go hungry"
"Woe to you who laugh now, for you will mourn and weep"
"Woe to you when everyone speaks well of you, for that is how their ancestors treated the false prophets"
Luke 6:24-26
The law of the harvest is insert in the plan of God, the law of the harvest is the "for", you live a spiritual gift there is a "for" that is a blessing, for a sin instead the "for" is a curse.
In essence the Bible explain to us that there are two mentalities, two paths and two retributions we have to choose between good and evil, between two moods of discern.
