Blessed because? or just blessed

We are moving into a new church facility. YAY! But that isn't what this blog is about.
I was speaking to one of the members of the church that formerly owned the facility, and we were discussing the changes we had made in the building. He was talking about how a few men from the church had met every Saturday morning to finish out a portion of the building.
I responded, "That is so awesome! We are so blessed because we have several contractor-type people who have volunteered their time to help us finish out the building".

For some reason, that thought stuck out in my head, and a few hours later, I heard myelf thinking..."Why do we as christians say 'I am blessed because', rather than just 'I am blessed' period?" Is being blessed about being able to show tangible benefits to others? Is it me, or should being blessed be about more?

I think about myself. I don't own a home, but I have a comfortable roof over my head. Does that qualify me as blessed? Then, I consider the single mom who struggles to pay her bills, but her electricity works. Does that qualify her as blessed. What about Bill Gates? Does he have an extra portion of blessing because he can show a tangible bottom line?

So, this stream of thought begs the question...If we are blessed "because...", then does that mean that blessings are earned? If so, can we launder our own filthy righteous rags?

I guess what I am trying to say is that, I don't want to say that I am blessed because I can show how what I have is a "better" blessing than the provision that God has made in your circumstance. I hope to be a pesson who can just be blessed, without any kind of proof necessary to validate my opinion.
