Sin is in every man.
The consequences of that universal sin is eternal death, that is, separation from our Creator forever. There is no way that man's actions can redeem him from this inherent sin. That would require a perfect life, which no man is capable of. While God cannot tolerate sin in heaven, He holds infinite love for His children. So that even while we continued to sin, He sent His son, Jesus Christ, to die for us and carry the burden of our sins so that we might have eternal life with the Father.
