I was born in the CRC church and baptized as an infant. Now I attend a non-denominational church that requires adult public baptism at the beach as pre-requisite for membership. I no longer piggy-back on my parents faith, I have my own personal relationship with Jesus. I'm not religious, I'm a follower of Jesus. So my question is: What role does adult baptism play in Christianity? Specifically, how is this different or needed in addition to, or in place of, infant baptism.
I'm obviously aware of the cognitive difference between infant and adult, and the understanding of the process that is being under taken, but what does the Bible have to say on this topic?
Thank for the help!
