Abraham said of his wife Sarah, “She is my sister.”

Genesis 20:1-18
Now Abraham moved on from there into the region of the Negev and lived between Kadesh and Shur. For a while he stayed in Gerar, and there Abraham said of his wife Sarah, “She is my sister.” Then Abimelek king of Gerar sent for Sarah and took her.
Now Abimelek had not gone near her, so he said, “Lord, will you destroy an innocent nation? Did he not say to me, ‘She is my sister,’ and didn’t she also say, ‘He is my brother’? I have done this with a clear conscience and clean hands.”
Then Abimelek brought sheep and cattle and male and female slaves and gave them to Abraham, and he returned Sarah his wife to him. And Abimelek said, “My land is before you; live wherever you like.”
Then Abraham prayed to God, and God healed Abimelek, his wife and his female slaves so they could have children again.
Many take this story as a duplicate of 12:10-20, though Abraham would not be the first to repeat a sin in testing circumstances. Nor is he the only person to have been put to shame twice before those with 'no fear of God' to guide their actions. Abimelech comes out of this more honorably than the man of faith. Once again we are held in suspense. Will God allow Abraham's folly to wreck his plan at the eleventh hour?
Why?
Abraham once again does the same folly things as he was in Egypt. Abraham feared he may be killed for his wife Sarah. Sarah was 89 years old but she was still beautiful. Abraham was 99 years old. 13 years ago Abraham has a son, Ishmael.
Once time God saved Abraham in the dream of Abimelech.
Because Abraham is chosen by the Lord, but face to the dead, Abraham lost his faith to the Lord. This is his weakness in his life.

亞伯拉罕一直過不了關的是沒有兒子和面臨生死關頭。我們也是否和亞伯拉罕一樣嗎？我們每個基督徒也都是相信神的。但是面臨許多關頭有誰可以勝過。這位被稱為信心之父，也有跌倒的時候。勉勵我們即使跌倒仍然要站立起來，神一定保守看顧。他沒有兒子，神一定會保守他的性命。應許還沒有實現，其實是在保護我們。
我們在一些犯難中一直想做些事情才會放心，常常做了反而壞了事情。人要插手幫助神反而更糟。有生命危險也是他自己想的。面臨困難我們沒有作為嗎？不是，但是我們當心正手潔！不要讓神擔心，不要走世界的路，違背神的旨意，走在神的心意中。神必保守看顧。

How?
All of us has weakness in our life, pray to the Lord and keep our faith to the Lord.
