There is contrasts between (a) revelation versus revelation; (b) heir versus heir; and (c) worship versus worship.
(a) The site at Shechem
is a special site—a religious site. It was probably a sanctuary. In any case, one could find the great tree of Moreh,
a fortune‑telling tree there. Priests could, for instance, predict the future from the rustling of the leaves. In contrast with that, Abraham lived with the Word, the revelation of God, the Lord, who had appeared to him
(Genesis 12:7). He had to avoid the Moreh religion. This made him even more of a stranger. And just like our father in faith, we as Christians are also strangers in this world (1 Peter 1:1; 1 Peter 2:11; and actually the whole letter)!
(b) God promised the land of Canaan to Abraham (Genesis 12:7). It was only a promise. Abraham had to believe it. In real life: At that time the Canaanites were in the land
(Genesis 12:6). Abraham had to depend on those people; he had to negotiate for pasturage; he had to buy food. So the question is: whose land was it? What did the promise mean to Abraham? Here on earth we too are children of Abraham: we are waiting for the new world (Hebrews 11:9–10; Isaiah 65:17–23; Revelation 21:1–5).
(c) For the Canaanites the site at Shechem was a place of worship. At that site and opposite it, Abraham built an altar for the Lord. He openly confessed his faith! He is an example to us; we should also not be ashamed of the testimony about our Lord
(2 Timothy 1:8) and always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you
(1 Peter 3:15).
6 Abram passed through the land to the place at Shechem, to the oak of Moreh. At that time the Canaanites were in the land.
