2"I will make you a great nation. I will bless you and make your name great, and you will be a blessing. 3 I will bless those who bless you and whoever curses you I will curse. All people on earth will be blessed through you."
Abraham had an open heart to God. He listened and obeyed revealing His love and respect for God. I don't know if that is why God chose Abraham to bless unlike anyone else on earth. Maybe Abraham was created for this blessing, but even then it would not have happened if Abraham did not choose to listen and obey.
This promise is a blessing that carries on to every generation after Him. God formed his nation through Abraham. Abraham did become famous. Here hundreds of years later you still know who Abraham is. Abraham was a blessing unto other people. He did many things for many people. He avoided conflict that could negatively affect relationships. If he could not avoid it, then he found the best solution.
Anyone who went against Abraham did not fare well. Anyone who went against God nation was eventually destroyed. Anyone who goes against God's people today will be dealt with by God. You know it does not end well for them. To live without Jesus is a cursed life. It will not end well.
You need to forgive those people now and try to introduce them to Jesus through your lifestyle. This is how you can carry out the Abraham Covenant today in blessing other people. Do good where you can do good. Do not be a push over, but do not go out of your way to make life worse or harder for anyone. Give what you have to give to those in need. Trust God to take care of you like He did Abraham and watch the blessings happen.
God set Abraham for his promise of blessings before Abraham even left his home country. God knew He would be obedient. Maybe Abraham needed to have hope before he left everything and everyone he knew other than his wife and nephew, Lot. Either way God commanded and Abraham obeyed without hesitation. God know you. He knows the best way to communicate with you. You only have to listen and obey like Abraham.
This promise that God made to Abraham covers progeny, prominence, and protection. God never promised wealth, but Abraham got that too. God only gave him one son, but through Isaac the nation of Israel came about over time. It was through God's nation came Jesus. It was Jesus that opened the door for salvation for every person of every nation. The promised was one based on righteousness and faith not law. You can see the significance of this promise made by God to one person that affects all people over time.
