Abram abandoned his security and his hitherto known world. As we have seen, he did not completely obey and took with him those who were not to go with him, but the main thing he did - he set out on a journey. We do not know if he had visited such far places before, but at all events he had given up his previous life. It was almost certain he would not ever return back.
The new situation meant that he became a head of the group, which travelled eastward. Now it was up to him to determine where the caravan would settle, when they would move on, but gradually he also began to determine other things. Sooner or later, he must have told his loved ones about a powerful encounter with an unknown god and his promise. His worship - but their also - has changed, and it is clear that not only Abram but the whole group stopped worshipping other gods. It must have been an uneasy step for the other members of the caravan, who, unlike Abram, had no personal experience with God! Certainly, some disputes broke out around it (as an important element of every cult is the fear of punishment). This proves that Abram in reality possesed great authority in the group.
At the same time, he did not know God in many ways at this time. It is remarkable, however, how quickly he understood the content of the first commandment from the very beginning: this God can only be honored only as one. You can't have other gods beside him.
