Overcoming Common Leadership flaws that were found in some Biblical Characters: Abraham’s fears that hurt his marriage and credibility

On two different occasions Abram/Abraham found himself fearful of his own safety when moving into foreign territory (Genesis 12 & 20). In each of these situations his fear centered on his insecurity of keeping his wife; thinking that someone in Egypt, or the Negev, would be able to just take his wife away from him and kill him. 

He convinced his wife to say that she was his sister and that would preserve his own safety and well-being. In both situations his wife was taken away to be the wife of the local 'strong-man' until God revealed the truth of the situation directly to the local king/chief. 

On each occasion Abram/Abraham was chastised by the local king/chief and Sarai/Sarah was returned to her husband. 

Abraham had a 'whine' that became unrespectable for Sarah. She became harsh and demanding toward Abraham. He also developed a reputation among the tribes of the Negev as not being credible, even in terms of the ownership of water wells. 

People who are more concerned with their own personal survival and well-being are fatally flawed. Their leadership will leave others in danger, insecure, without trust, and bitter. 

If you observe that someone puts himself/herself before their family, you should always have reservations of that person's trustworthiness and credibility. Self-centeredness is based upon fears and insecurities - which will always leave others twisting in the wind. 

What about the New Testament statements about Abraham's 'righteousness?' Abraham grew into being 'counted' worthy of 'righteousness,' but many millions of people have suffered for his earlier character flaws...Hagar's story was that of being victimized by a weak and manipulative man trying to survive the storms of his situation the easiest way possible and not doing what was 'right.' 

The 'children' of Israel continue to suffer because of Abraham's character flaws of fear and insecurity.
