Christianity vs. Religion

A couple of weeks ago the pastor of my church made a great point.
He said that you spell religion D-O
You spell Christianity D-O-N-E

What a simple way to explain it. All world religions minus Christianity require works to attain salvation. With all other "religions," you must pray certain prayers, reach a higher level of enlightenment, be at church every week, give a certain amount of money, do more good than bad, and so on and so on.

There is ONE faith that stands alone: Christianity.

It is not a lifestyle.
It is not a set of rules to follow.
It is not a way of morality.
There is nothing you can DO to be saved because it was DONE on the cross. As Jesus said on the cross, "It is finished."
I could never do enough good things to stand before the Holiness of the Perfect God. Thankfully, Christ did it all. It is DONE...there is nothing more I can DO...but choose to surrender.
