The greatest blessing in life is to know God Himself. One of the things about God that we have to be thankful for, is His great love that is extended to those who will serve Him and love Him in return. You are blessed because you are SAVED! It is worth letting that word sink in.
Paul puts it better in Romans 8:1 "Therefore, there is now no condemnation for those who are in Christ Jesus." Consistently, the Bible refers to the gifts that God gives, whether material or spiritual, as blessings. Therefore to bless someone is to ask divine favour on that person. Usually, the person of higher status blessed the one of lower status.
But since a blessing expressed the desire for a person's well-being, it was also used as a formal greeting, even from an inferior to a superior (Gen. 47:7-10; Ruth 2:4). A blessing could also become an expression of praise, and in this sense, grateful people can bless God ( Psalm 103:1).
The blessings that people in Israelites families desired most was the prophetic announcement by which the head of the family passed on favours to his children.
Probably, the most striking example of a blessing carrying with it the power of certain fulfilment was God's blessing to Abraham that promised him a people and land.
From the passage read, these blessings were connected more with the life of the people as a whole and were directly dependent on the people's obedience or disobedience.
The blessings mainly concerned agricultural prosperity, family happiness, victory over enemies and honour in the eyes of other nations. God’s assurance that He would supply their needs was linked to a warning. They were not to look for family increase or agricultural productivity by worshipping other gods.
So the blessings are promised upon condition that they diligently obey the voice of God. God promised to pour out blessings on His people. God does not promise His people unending health and wealth or success. In fact, the Old Testament saints often experienced the opposite, and the New Testament contains numerous predictions of suffering for followers of Christ.
We experience a unique peace and joy in the daily moments of our lives, even while surrounded by trials and sufferings, and in the end, we receive God's eternal blessings stored for us.
These are God's blessings for us and they are found in Deuteronomy 28: 1 - 14.
