Genesis 20:8 says, Therefore Abimelech rose early in the morning, and called all his servants, and told all these things in their ears: and the men were sore afraid.  After God had spoken to Abimelech in his dreams, he got up early and called his servants and told them what had happened.  Abimilech didn't just claim he had a bad dream, but he actually knew that God had spoken to him.  I believe that when God speaks to a person, whether they profess to know Him or not, they will know.  Verse nine states, Then Abimelech called Abraham, and said unto him, What hast thou done unto us? and what have I offended thee, that thou hast brought on me and on my kingdom a great sin? thou hast done deeds unto me that ought not to be done.  Abimelech called Abraham and asked him why he had done such a terrible thing to him.  Abimelech said that Abraham had brought a great sin to the kingdom.  We, as followers of Christ, should never be guilty of leading others into a sinful situation.  Verse ten asks, And Abimelech said unto Abraham, What sawest thou, that thou hast done this thing?  Abimelech asked Abraham what he had seen concerning Abimelech and his people that had caused Abraham to do this.  That was Abraham's problem.  He was looking at the power of Abimelech instead of the power of God.  We should never allow anything in this world to become more powerful to us than God is.  Verse eleven states, And Abraham said, Because I thought, Surely the fear of God is not in this place; and they will slay me for my wife’s sake.  Abraham said that he believed that Abimelech and his people did not fear, or know God, and he was afraid that they would kill him and take Sarah.  If Abraham had put his trust in God, he would not have been afraid.  He acted out of a self made fear.  We today should never allow our personal fears to cause us to make our own way of dealing with a situation where we might possibly be in danger, but must always put our faith in God.  We certainly should never do anything that would be against God's law simply because we are afraid.  Verse twelve adds, And yet indeed she is my sister; she is the daughter of my father, but not the daughter of my mother; and she became my wife.  Abraham was still trying to justify his actions.  He said Sarah was both his wife and his half-sister.  We cannot justify sin by half truths.  We must be totally honest in our relationship with others, and especially with God, no matter what it might cost us in this world.  Verse thirteen continues, And it came to pass, when God caused me to wander from my father’s house, that I said unto her, This is thy kindness which thou shalt shew unto me; at every place whither we shall come, say of me, He is my brother.  Abraham said that God caused him to wander, but the plan to call Sarah his sister was strictly his plan.  After all God had done for him and the promises that God made him, Abraham was still lacking the faith to totally trust God.  When we become a follower of Christ, we must live by faith in God's promise that we are His children forever.  Verse fourteen says, And Abimelech took sheep, and oxen, and menservants, and womenservants, and gave them unto Abraham, and restored him Sarah his wife.  Once again, Abraham benefited materially from his deception, but I believe that he suffered spiritually.  Even if we were to gain materially, we can never afford to go against God's will and teachings.  Verse fifteen adds, And Abimelech said, Behold, my land is before thee: dwell where it pleaseth thee.  Abimelech told Abraham to take his choice of the land to dwell in.  We can never allow the end to justify the means if we are going against what God's law.  Verse sixteen states, And unto Sarah he said, Behold, I have given thy brother a thousand pieces of silver: behold, he is to thee a covering of the eyes, unto all that are with thee, and with all other: thus she was reproved.  Abimelech then told Sarah that he had paid Abraham for his actions concerning Sarah.  Verse seventeen declares, So Abraham prayed unto God: and God healed Abimelech, and his wife, and his maidservants; and they bare children.  Abraham prayed for Abimelech and God healed him and his people.  Though Abraham had been the reason for the sin, when he prayed to God, God granted his request.  Had Abraham prayed for Abimelech and his people before hand and trusted God to keep him safe, the whole situation could have been avoided.  As followers of Christ, if we cause someone to fall into sin, we must first confess to God and then pray that God will heal them.  Verse eight adds, For the LORD had fast closed up all the wombs of the house of Abimelech, because of Sarah Abraham’s wife.  God restored the ability of the woman to have children, which had been taken away because of Sarah.  Sarah and her son with Abraham was still God's plan to make a great nation of Abraham.
