Genesis 12:3 “And in you [Abraham], all the clans of the earth will be blessed.”
YHWH promised Abraham to make him a great nation and to bless him and his descendants, so Abraham left as YHWH instructed and He multiplied his offspring and Abraham then became the “father of many nations.”
Berĕshith (Genesis) 26:5 TS2009
because Aḇraham obeyed My voice and guarded My Charge: My commands, My laws, and My Torot.”
Abraham's belief was counted to him as righteousness because his faith worked together with his works. Abraham set the example of what a true believer is. Those who are of "belief" are sons and daughters of Abraham and heirs according to the promise.
Acts 2:39: “For the promise is to you and to your children, and to all that are far off, as many as YHWH, our Elohim, shall call.”
According to Acts 1:4, Yahshua instructed His disciples to wait on the promise of the Father - the Ruach [Spirit] of YHWH - the blessing of Abraham. They would receive power when the Ruach would come upon them and be filled with YAH’s Set-Apart Spirit enabling them to perform mighty works and speak in other tongues [languages], which was spoken by the Prophet Joel [2:28].
In the last days, believers will also prophesy and dream dreams like the original Hebrew prophets and will receive the blessing of Abraham, but cursed is the one who does not continue in all that is written in the Torah, to do them.
Torah defines sin but does not have the power to make someone obey it; yet, the Ruach Hakodesh empowers us and equips us, as believers, to walk according to His will and to be witnesses to all the nations and proclaim the Good News message to all who will accept the invitation.
Acts 5:32 “And we are His witnesses to these matters, and so also is the Set-apart Spirit whom Elohim has given to those who obey Him.”
Our obedience cannot be apart from belief in Yahshua. It takes both faith and obedience to the Father’s commandments. When we obey, we receive the Spirit of Truth and the blessing of Abraham, and anointing just like Yahshua, to bring the Good News, to heal, and to help release and set the captives free.
1 Corinthians 12:7 “We are given the manifestation of the Spirit for profiting” or, for the benefit of others and for ministry. We receive wisdom through the Spirit and to another, knowledge, and other gifts, and works all these according to the same Spirit.
YHWH will reveal Himself to those walking in His will. Wisdom and other gifts come from the Ruach for the benefit of others and for ministry, which glorifies our Father in Heaven.
Luke 11:13 “If you then, being wicked, know how to give good gifts to your children, how much more shall your Father from Heaven give the Set-Apart Spirit to those asking Him!”
The blessing of Abraham is available to believers of all nations.
Galatiyim (Galatians) 3:29 TS2009
And if you are of Messiah, then you are seed of Aḇraham, and heirs according to promise.
