That night the Lord appeared to him and said, "I am the God of your father Abraham. Do not be afraid,
for I am with you; I will bless you and will increase the number of your descendants
for the sake of my servant Abraham."[Gen. 26: 24]

I suggest you approach your reading of the Bible with David Bosch’s conclusion in mind:
“The Christian faith is a historical faith.  God communicates his revelation to people through human beings and through events, not by means of abstract propositions.  This is another way of saying that the biblical faith, both Old and New Testament, is ‘incarnational’, the reality of God entering into human affairs.”

Our God is not interested in us speculating about him.  He makes it clear from the way he inspired the Bible that he wants us to know him in a practical, on-going relationship.  Even in the OT He enters into our world and meets us in the day to day events of life.

So as you read the Bible look for how God or his angels greet people.  As the scripture above shows, heavenly messengers go out of their way to reassure the people that God is with them and for them.  Here is another example:
“I am with you and will watch over you wherever you go, and I will bring you back to this land. I will not leave you until I have done what I have promised you."  [Gen 28: 15]

God has chosen to reveal himself as the God-who-is-with-us-and-for-us for good reason. 

1. God in himself is unknowable to humans.  We do not have the equipment or apparatus to see an invisible God.  Our limited minds cannot fully grasp an unlimited Being. So God puts the spotlight on knowing him in terms of how he deals with humans.  In other words, all that we know about God comes from his relationships with his physical creation. God enters into the ordinariness of our lives and makes himself known in that way.
2. In the pressure of life most people are not interested in proving or disproving the existence of God.  Our concerns are much more practical – and self-centered – than that!  Most people only want to know, “If there is a god or some “higher power” is he with us and for us?”  Or as the water-starved Israelites put it when they found themselves in a desert, “Is the Lord among us or not?”  (Ex 17: 7).  The Israelites are simply asking the anxiety-driven questions that lie in the heart of all humans, Are you with us or for us?  If so, prove it!  For most people, God is only important if he is on our side!

And the Bible reveals a God who is more than willing to meet us where we live – and to answer those two questions that are so important to us.  The Old Testament is the record of a God who seems intent on answering precisely those two questions – Is God with us?  Is he for us?  In fact, when Israel failed to adequately live as the representative of the God-who-is-with-and-for-us, God himself came!  And, in that ultimate expression of his willingness to incarnate himself, he gave himself the name Immanuel, God with us (Matt 1: 23) who is for us (Matt 1: 21).

As you read look for examples of how God answers our need to know that he is with and for us.  Here is a sampling from Genesis and Exodus of the various ways God assured different people:
Gen 21: 17-20             24: 40              26:   3              31:   3             
Ex     3: 12                  19:   9              25: 22              29: 42              33: 14-17
