“… say that you are my sister so that it may go well with me because of you, and that I may live on account of you…” – Genesis 12:13.
“…Abraham said of Sarah his wife, ‘She is my sister.’ So Abimelech king of Gerar sent and took Sarah…” – Genesis 20:2
“ … When the men of the place asked about his wife, he said, ‘She is my sister,” for he was afraid to say, ‘my wife,’ thinking, ‘the men of the place might kill me on account of Rebekah, for she is beautiful.’” – Genesis 26:7
We should attempt to learn a valuable spiritual lesson from these texts. What can we find out about ourselves noting the sins of those who lived before us? The New Testament indicates that sins were recorded in the Old Testament for our benefit so that we can avoid the same mistakes and consequences (1 Cor. 10:6-12).
One aspect of our sin, as we have seen from this lesson, is its enslaving power. Sin has tremendous consequences for not only the person who commits it, but on others as well. Sin becomes a habit or even an addiction. As in the case of Abraham, having lied about Sarah, saying he was his sister rather than his wife, with the result that Pharaoh took her as her mistress. Later Abraham repeated the same lie to Abimelech. It appears he did not learn anything from the first incident. And the sin pattern was passed down to his son Isaac who repeated the same lie with regard to his wife, Rebekah. One sin leads to another sin as we have seen in not only these men’s lives, but in others too. For example, after killing Abel, Cain felt constrained to lie when God asked him where his brother was. Sometimes a larger sin is required to cover a smaller one. Having committed adultery, David found it necessary to commit murder to conceal what he had done.
In conclusion, the Bible teaches that the entire human race consists of people who are slaves to sin (Romans 6). We are all sinners (Rom. 3:25). The only hope of liberty from this bondage is in the sacrifice of the cross of Christ, who shed His blood to set the captives free. We are released from our sins by Jesus’s blood (Rev. 1:5). He has reconciled us in His earthly body through His death (Col. 1:22). Christ appeared once for all to put away sin by the sacrifice of Himself (Heb. 9:6). Sin’s grip on man is loosed by His work on the cross: “For the law of the Spirit of life in Christ Jesus has set me free from the law of sin and death” (Rom. 8:2).
If we are in Christ we do not have to fear the condemnation of sin and its results for only then are we truly free (Rom. 8:1; John 8:31-36).
