Many great men of God stand out in the Bible. There was Moses, the great lawgiver. Joshua, the powerful military leader. David, the greatest king Israel had ever known. Elijah, one of the great prophets. Peter and Paul were mightily used of God. Yet all of these looked to Abraham as a man of faith. God's friend! When we are introduced to Abraham, God has told him, "Get out of your country, from your family and from your father's house, to a land that I will show you." - Genesis 12:1.  Abraham was raised in a pagan culture. God knew that for Abraham to stay would be detrimental to his spiritual growth. His family and friends would not help, but hinder, him.
Jesus said to one individual - "No one, having put his hand to the plow, and looking back, is fit for the kingdom of God." - Luke 9:62. In the same way, God was essentially saying to Abraham, "You have to make a clean break now if you are going to move forward spiritually." And God's plan for Abraham was, "I will make you a great nation; I’ll make your name great; and you shall be a blessing."  - Genesis 12:2  Have you noticed that the Lord's commands are rarely accompanied by reasons, but they are always accompanied by promises? There are times when God will speak to you and it may not make complete sense at the moment. When the Lord told Noah to build the ark, it didn't make sense at the time. But it made perfect sense later. Many times we think we know better than God. He tells us to turn away from sin and from people who could drag us down spiritually. If we do, He will bless us.
Unfortunately, this is not what Abraham did. He sort of obeyed. God told Him to leave his country, separate himself from his relatives, and go to a land that God would show him. Abraham left his country, but he didn’t separate himself from his family. Nor did he go where God told him to go. Until Abraham obeyed God - we read of no further command from God. Has God told you to do something? Have you been dragging your feet? Partially obeying? Partial obedience is actually disobedience. When God tells you to do something, you need to do all of it - not just what you agree with or are comfortable with. We need to do God's will in God's way and in God's time.
