No you don't.
Yes I do.
The former renew the mind in Christ with great profit, and the latter exercise the mind in Scriptural things, with a little profit. Sort of like godliness is profitable in all things, whily bodily exercise profiteth little.
Now as far as the topic of Christ's blood, it isn't like there is a shortage of scriptures on the topic. And that is where the topic should start.

Now I am not opposed to singing a hymn with you about the incorruptible blood of Christ.
I am not oppose to you explaining why you think Christ had incorruptible blood....or that it was because of His blood that He could not sin. I can go with that Christ's blood being incorruptible as unperishable....as in an artifact.
There are things about Christ's blood I believe that are outside of the Bible. But I am not a fundamentalist and I say the source of the belief.
I believe any of the cloths or rags that touched Christ during the Passion had miraculous powers.
I believe in the Veil of Veronica
I believe in the Shroud of Turin
I believe in a few of the Christ artifacts.
But direct biblical support is another thing.
