Is Tolerance a Virtue?

When Jesus gave His life on the cross He did it to provide forgiveness of our sin. I do not believe He shed His blood to condone our sin! Yet, even in the church, there are those who are all to willing to turn a blind eye to sinful behavior. They do it thinking that they are taking the intellectual high ground. Somehow, in their mind, they believe tolerance is the greatest virtue. One thought occurs to me....If Jesus preached tolerance of sinful behavior, there would have been no need for Him to have given His life. My opinion of course! :)
