What about sin?
We cannot close our Bibles and say, This has got nothing to do with me. In Genesis Ch. 5:3-4 we read, "When Adam had lived 130 years, he had a son in his own likeness, in his own image, and he named him Seth. After Seth was born, Adam lives 800 years and had other sons and daughterst"
These verses tell us that during the remainder of their lives Adam and Eve had several children. The Bible gives the family tree from Adam to Noah, and then to Abraham, Isaac, and Jacob. Twelve generations later we come to King David, then to the end of the Old Testament and then to the beginning of the New Testament, and since that, you and I were born. This means you and I are linked to Adam. We are his direct descendants. Our family tree goes back in an unbroken line to the first man who ever lived on the earth.
Now, what are we told, "Adam had a son in his own likeness, in his own image." Do you remember when we met that kind of language before? It was in Genesis Ch.1:27 where we read that, "God created man in His own image, in the image of God He created him." We saw that man was made in the moral image and likeness of God. He was created to be like God in righteousness and holiness. That same phrase "in his own likeness, in his own image" is now used of Adam's son, and by implication, of all his other sons and daughters.
Adam's children - the first of whom was born after Adam and Eve had disobeyed God and fallen into sin - shared Adam's nature and character; their state was now the same as his in the sight of God. Adam's corrupt nature was therefore transmitted to every generation that followed. As he was cut off from God, separated by his sin, so, as a result, all his children and descendants from that day on began their lives in the same condition.
Adam stands as the federal head of the human race. When he failed and when he yielded to temptation and fell, the generations yet unborn fell with him. Even Adam's second son was a murderer.
As soon as Adam and Eve sinned they witnessed God's anger and hatred of sin - a curse was put upon the ground and the woman with pain would give birth to children. Sin entered the human race through Adam, and the human race has been trying ever since to make amends, but without success. We are all sinners by inheritance, and, try as we will, we cannot escape our birthright. The fall of our first parents has had its effect upon the kind of people we are today. We are sinners. We have a natural tendency to listen to the devil and to disobey God. Instead of serving God in freedom, man has become a slave to sin.
