The life of Abram

As I spoke in reflection to my first Bible reading it was clear to me that the causality of this universe, earth and life on it, the cause is clear in Genesis. When I get to the the life of Abram we start to see what truth really is. It is abundantly clear he was to live by truth placed by God. Although far from a flawless knowledge of truth Abram through his obedience to the absolutes was seen highly by God and called later in Genesis, Abraham. As a symbol of His pledge, God changed Abram's name to Abraham, which means father of many nations. Abraham knew what the truth was, he knew the laws that where put on every humans heart.
Abram knew what the Lord expected of him and although he did not know exactly Gods plan for him, Abraham had the freedom to live as he wished – But he rather used the freedom to live as he ought. As he ought to live????? Ought, according to whom? or what? is the question that is now being asked. Who decides how we ought to live?
Is truth what we perceive as truth? is it what society, actively believes is true collectively? Or is it something outside of ourselves that exists rather we are here to know truth or not? Truth, It involves not only the willingness to act according to God's truth, but also depending on God to perform his will for us. God promised to give Abraham the land, yet when Abraham got to Canaan, he found that others already owned it. Abraham did not try to buy it, even though he had the means to do so (13:2). Abraham did not try to use force to take over the land although he may have been able. He waited, living in a tent, walking the Promised Land his entire life. When Sarah died, he had to buy a burial plot for her (chapter 23) even though God had promised him the whole land. God said "Go to the land" , "I will give you the land."
Abrahams truth was Gods truth. But if truth is relative to what we perceive or society says is truth we cannot survive, beacause it is not absolute, it is a created belief system within ourselves or by what others tell us is truth. Conveyed simply, God cannot lie, Gods word is truth and it exists rather we use our freedom to seek to listen to what His truth tells us or not.
