CANIS,
When Adam sinned his sin was imputed to the whole human race. All mankind is separated from God by sin. Maybe that doesn't seem right to man, but because of this principle of Federal Headship the obedience of Christ and His sacrifice for our sins, that is He paid the price for our sins, His righteousness is imputed to those who come to Him in faith (born again.) In fact the entire human race is under the wrath of God. Only those who are in Christ are spared from God's wrath, and that is because of His righteousness. The solidarity of a people or the race is seen in the case of Achan. See Joshua 7:1, 11. Note that God said that Israel had sinned and Israel had been defeated as a result of one man's sin. Children are not innocent. It was God's judgement to wipe out the whole of the Canaanites. God holds all mankind guilty and the only way to Him is through Christ. This is the reason that all religions except Christianity are hopeless as the way to salvation. Paul covers this doctrine of Original Sin and Federal Headship in Romans chapter 5. I will post some of it. Romans 5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned: 15 But not as the offence, so also is the free gift. For if through the offence of one many be dead, much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many. Romans 5:17 For if by one man's offence death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ.) 18 Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life. 19 For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous. 21 That as sin hath reigned unto death, even so might grace reign through righteousness unto eternal life by Jesus Christ our Lord.
Finite, sinful man cannot comprehend the infinite and holy God. He only is the standard. He is neither arbitrary nor unfair. All deserve Hell. However, in His love He has made a way to Himself. It is a simple way, the way of the Cross. It is through faith in Jesus Christ who God sent to pay the price of our sin. God has pronounced death to the soul that sins. All have sinned. When we come to Christ He considers that we died on the Cross with Christ and our sins are imputed to Christ and His righteousness is imputed to us. We are then children of God and our eternal future is assured by the righteousness of Christ. There is no other way. It is the way that God has decreed. There are references tko Jesus. Josephus, the Jewish Historian AD 37-100 mentions Jesus. There is much evidence as to the person and works of Christ. I wish space permitted more discussion rgarding this.
