Abram to Abraham

"The Lord said to Abram after Lot had parted from him, 'Look around from where you are, to the north and south, to the east and west. All the land that you see I will give to you and your offspring forever. I will make your offspring like the dust of the earth, so that if anyone could count the dust, then your offspring could be counted. Go, walk through the length and breadth of the land, for I am giving it to you.'

So Abram went to live near the great trees of Mamre at Hebron, where he pitched his tents. There he built an altar to the Lord." Genesis 13:14-18

Every time I read the Bible, I try to think about how it can be applied to us in the modern times. Not in the sense of prophetic guidance, but as what God wants to say to us. 

When I read this section, I wondered what it is that I should be thinking. I am hesitant to say that God will bless us, so go on living, for that would be faith only for the want of success. 

What is it?
