[sammyg2]

Jesus did come to forgive and sacrifice himself for our wickedness, but he did not tell us to ignore the old testament:

"Do not think that I have come to abolish the law or the prophets. I have come not to abolish but to fulfill. Amen, I say to you, until heaven and earth pass away, not the smallest part or the smallest part of a letter will pass from the law, until all things have taken place." (Matthew 5:17)
