When speaking of Abraham’s blessings, it refers to the blessings of the family or the generation of God. Galatians 3:9 tell us that those who have faith in Christ are blessed together with Abraham the man of faith. Take note that it does not say they are blessed through Abraham, but blessed with him. This is said because when a person receives Jesus in their lives, this person becomes part of God’s family, therefore he is blessed with the blessing that Abraham was blessed with because this blessing is given to all who are part of God’s family.
Galatians 3:16, tell us that the promises of God were made to Abraham and his seed, and it speaks of one seed and that is Christ. We have been made part of Christ in the new covenant; therefore all of God’s promises are ours in Christ. All the promises made to Abraham and those that appear in the old covenant are ours in Christ. They are realities that we enjoy in Christ. They are not just promises because Christ came to take all of Gods judgments and all the curses that came as a result of sin to be atoned for with his life so that could fulfill all of God’s promises for us Therefore Gods promises are perfected in Christ, they are not just empty promises but they are truths and realities that we live in now. These truths are ours from the time that we receive Jesus Christ into our lives (2Corinthians 1:20). Jesus Christ came to take all the curses that came with sin and the law and he fulfilled all of God’s promises for the good of those who accepted him. Here are some of Abraham’s blessings: Abrahams blessing are ours in Christ.
1) Receiving the Holy Spirit (Galatians 3:14). This is the biggest blessing of them all because when we have the Holy Spirit, we can have a deep knowledge of God and Jesus Christ. We can walk in the will of the Father in all things through the empowerment of the Holy Spirit. We are able to know all that God has given to us freely by His grace (1Corinthians 2:9-14)
2) Genesis 12:2-4, Its multiplication in everything that we do, fame, blessing, which is the empowerment to prosper, Protection from evil etc.
3) The earth as our inheritance (Romans 4:13, Genesis 15:18-19).
4) Genesis 13:2, multiplication and increase of physical things e.g. money, clothes, cars etc. God wants us to have plenty so that we become a blessing to others (Genesis 12:3).
5) All of God’s promises in the old and new covenant are the blessings of Abraham, and they are ours in Christ.
THE WORK OF MOSES
Moses’ work was to bring the order of God to His people at that time. His nation was Abraham’s physical children, which is the physical Israel. God founded the old covenant with Israel through Moses, which is the order of the law to the physical children of Abraham. The covenant of that nation was used for a short period of time until Jesus Christ came. We have clarified why God gave the covenant of the law earlier. In other words, at that time, if a person was interested in becoming part of God’s nation, he had to obey the Law of Moses. But still, that time of the law was just a shadow of how God wanted to bless his true generation or family, which is that of sons and daughters. At the time of the Law, The Israelites were just people of God not sons and daughter as we are. Therefore at that time of the Law, God’s true family had not been birthed, but the physical Israel was just an example of how God was going to bless his true family of sons and daughters, this is why it is said that the promises are written for Abraham and Christ, not Abraham and Moses or the physical Israelites (Galatians 3:15-20). In other words, God was giving us a picture through his servants of how he wanted to bless his sons and daughters. This is why we can accept the promises of God from the old Covenant because He was demonstrating how he wanted to bless us as his sons and daughters. That is how He wants to bless us and even more than that because we are now His sons and daughters, and all that is His is ours as well. God had put Abraham’s physical children under the law because he had planned for the law to lead them to Christ, so that they too will no longer be servants but become sons and daughters of God in deed by believing in Christ, so that they become a part of the true family of God as well (Galatians 3:23-26). He had also given them the law so that they become aware that they have a sin nature in them when they were unable to fulfill the law of the Holy God, and that they realize that they need a savoir who would put them in right standing with God. The plan was still to point them to Jesus Christ because there is no one who can be put right with God by obeying the Law of Moses (Romans 3:20).
