Get baptized under the authority of a local NT church, not by someone you like in a lake or stream somewhere. The flippant attitude by some about baptism is unbelievable, but then again, no, it isn't unbelievable.
Acts 2:41 "So those who received his word were baptized, and there were added that day about three thousand souls." It does not say, maybe there was a river close by, but in 2000 I do remember seeing any rivers close by.
Acts 8:36 And as they were going along the road they came to some water, and the eunuch said, “See, here is water! What prevents me from being baptized?” All you need to be baptized is water.
Formal baptismals are from the RCC, Scripture say nothing about a formal place or classes to go throught to be baptized. The eunuch seen a body of water and Philip baptized him.
