Does too many strong links have negative effect?

[kingp]

Here is my query about backlinks. Does too many strong links if linked towards my site all at once then will it effect my site's SEO negatively?

The fact is in my link profile I already have some good links. But I want to get more organic traffic so I applied for guest posting on four blogs. And now they have accepted it. I will get four strong links out of them. Will google see them as a purchased links? I am a bit confused right no.
