Few people seem to understand the miraculous event that conversion is. If you understand and believe the Word of God, that is to no credit of your own. It is the work of God.
The attached message is from Paul Washer and addresses the wonderful power of God which alone can change the heart of man and open blinded eyes. The only thing I would add to this is that upon truly being born again, the life birthed within you by the Spirit transforms you into a new creation.
You could never work your way into salvation or even try to "live holy", that is just religious works. Yet the true testament of the Spirit that a conversion has taken place is that the old things really have passed away; we have truly put on the new man and are living for Jesus Christ.
