God promised He would bless all nations because Abraham obeyed him by keeping all His requirements, commands, decrees and laws. That same blessing was passed on to Abraham's son, Isaac, and on to Isaac's son Jacob, and on to Jacob's offspring (Genesis 17; 26:2-5, 24; 28:13-15). “The promises were spoken to Abraham and to his seed. The Scripture does not say 'and to seed,' meaning many people, but 'and to your seed' meaning one person, who is Christ” (Galatians 3:16).

From the promise made to Eve (Genesis 3:15) through Abraham, Isaac, Jacob and the nation of Israel and spoken of by the prophets, God has repeated this promise and preserved it in writing so today all may hear and be given that opportunity to receive this blessing. Paul an apostle continued to explain:

You are all sons of God through faith in Christ Jesus, for all of you who were baptized into Christ have clothed yourselves with Christ. There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus. If you belong to Christ, then you are Abraham's seed, and heirs according to the promise.
Galatians 3:26-29

The blessing God gave Abraham has been passed on to people out of all nations who have placed their faith in Jesus the Son of God, the “seed” promised from the beginning.

Jacob had an older brother Esau who had first claim on the birthright and the blessing; but because he put a higher value on one meal than he did on his birthright, he sold it to Jacob. “So Esau despised his birthright” (Genesis 25:29-34). He serves as a warning to us today: “See to it that no one misses the grace of God and that no bitter root grows up to cause trouble and defile many. See that no one is sexually immoral, or is godless like Esau, who for a single meal sold his inheritance rights as the oldest son” (Hebrews 12:15-16).

Esau focused his desires on meeting his desires of the moment. We are warned:

Do not love the world or anything in the world. If anyone loves the world, the love of the Father is not in him. For everything in the world—the cravings of sinful man, the lust of his eyes and the boasting of what he has and does—comes not from the Father but from the world. The world and its desires pass away, but the man who does the will of God lives forever.
1 John 2:15-17

The author of Hebrews advises us: “Let us fix our eyes on Jesus, the author and perfecter of our faith, who for the joy set before him endured the cross, scorning its shame, and sat down at the right hand of the throne of God. Consider him who endured such opposition from sinful men, so that you will not grow weary and lose heart” (Hebrews 12:2-3).

Jesus must be our greatest love. “Anyone who loves his father or mother more than me is not worthy of me; anyone who loves his son or daughter more than me is not worthy of me; and anyone who does not take his cross and follow me is not worthy of me. Whoever finds his life will lose it, and whoever loses his life for my sake will find it” (Matthew 10:37-39).

If he were only a human being, these words would be the height of arrogance; but he was God, the Son of God, whose love for us was so great that He gave his body to death for us. He only asks of us the kind of love he has for us (John 15:9-17).

Jesus is the only “blessing” we need. His blessing is eternal life in his kingdom (Revelation 22:12-17).
