Do I need to be re-baptized?

I cannot remember simply because it was so long ago and memories fade. I do remember it being memorable at the time.  I remember being asked to reject Satan…

But you didn’t reject Satan.  You said you fell away.  You are a believer now?  Now, you’ve actually rejected Satan and his empty promises?

The name of Jesus was definitely invoked when I was baptized 20 years ago. A second one would seem unnecessary, no?  

Liver shivers don’t get you saved.  When did you actually turn from sins, head in the opposite direction and trust in the Lord?  Baptism is your first act of obedience.
