Matthew 5:27; "Ye have heard that it was said by them of old time, Thou shalt not commit adultery: 28; But I say unto you, that whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart. 29; And if thy right eye offend thee, pluck it out, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell. 30; And if thy right hand offend thee, cut it off, and cast it from thee: for it is profitable for thee that one of they members should persish, and not that thy whole body should be cast into hell."
Generally speaking I don't think people take commiting sin serious enough. The penalty for sin is death. The soul that sinneth shall surely die. Jesus died for the sinner, and He sets the sinner free, forgiving him of his sins. Jesus forgave the woman caught in adultery, and told her neither do I condemn thee, go and sin no more, after asking her about her accusors.
Are we to pluck our eye out and throw it away? Are we to cut our hand off and through it away. Jesus said it is better than we lose one of our members, such as our eye or our hand than to end up in hell with our entire body. In this context Jesus is talking about adultery. I think His reference to the eye is a reference to looking at what we should not be looking at. It is better not to look at it and go to heaven than to look at it and end up in hell. The hand represents doing something, and it is better not to have our hand help us commit sin, than to use our hand to commit sin and end up in hell. Jesus said that if a person looks on a woman and lusts after her, he has already commited adultery with her in his heart, and he has commited the sin for real in God's sight. This is what the Psalmist David did. He was a man after God's own heart because of his attitude and readiness to repent, but David looked at a woman who was taking a bath. It was not wrong that he saw her in that state, but it was wrong that he kept looking until he plotted to have that woman as his own to the extent that he commited murder to get her. He repented and was very sorry. He kept the woman as his wife, and what would be the purpose of losing her, because the deed had already been commited. David paid a dear price. He lost the child born from that lustful act. Then God's judgement was pronounced upon David in that God said that the sword would never depart from David's household. God did bless David inspite of that, but David still had to pay for that sin that he commited. If we could talk with David, no doubt he would tell us that he wished a million times that he would have lived a life that was free from sin. What do you think about this analogy?
