Many followers of Yahweh recognize the significance of accurately observing His sacred calendar. However, there seems to be widespread confusion about how to determine the beginning of a scriptural month.
We know that Abraham was justified to receive the Promised Land “because Abraham obeyed my (Yahweh’s) voice, and kept my charge, my commandments, MY STATUTES, and my laws.” (Gen. 26:5)
Observing Yahweh’s Festival Days is a statute that Abraham would have adhered to as a requirement for justification and obtaining salvation and eternal life.
One must also conclude that Abraham surely observed the Festival Days correctly; otherwise, he would not have fulfilled this requirement, and Yahweh would not have justified him.
