What did Esau despise on the day he gave up his birthright?

More than inheritance benefit, the birthright consists of succession of God's purpose for a generation, including all the spiritual benefits of what it means to be the firstborn of a caste.

How do I discover my function within the kingdom of God?

God explained to me that each one of us is trained in the area where we will develop our ministry. For example, the prophet needs to exercise discernment in order to be able to differentiate when it is God who speaks, and when the voice does not come from God, so his training is to eat butter and honey, so that he knows how to discard the bad and choose the good.
