Is sin relative ?

Last week there was a big buzz on television in India about gay rights. I was watching one of the televised discussions on it where the TV anchor was making fun of a pastor for having an alternate opinion. The point being that how can christians term something as wrong when the rest of the world feels it is not wrong to do so. It made me ponder about a very interesting question: is sin an absolute term ? or is it one that evolves with time and is dependent on the context ? If there is a God sin has to be absolute. To me sin is like the laws of nature, they have to be absolute. Just like the laws of nature your understanding/interpretation of it will depend on your knowledge of God. To me the fundamental principle is your Love for God and your willingness to live your life for Him. Anything that does not align with this fundamental belief becomes a sin. You will have to delight in his word and in understanding it. As per the Bible everyone is a sinner and hence no one has the right to judge others of their sin. God looks at our hearts and knows every thought that crosses our minds. All sins lead to death. We are saved by His grace and not by our actions. It is our duty to acknowledge the great sacrifice and love and live our lives for his glory. We have to be open to the notion of Holy Spirit convicting us of our fallacies, prejudices and our concept of sin within the context of God's word.
