In Acts 8:26-39, Philip was witnessing to a eunuch of great authority under Candice, Queen of the Ethiopians. Philip came preaching Jesus to him. As they went down the road, in the chariot, they came to some water, and the eunuch said, see, here is water, what hinders me from being baptized?  Then Phillip said, if you believe with all your heart, you may. And. he answered and said. I believe that Jesus is the Son of God. So both Phillip and the eunuch went down into the water, and he baptized him. If you believe in Jesus Christ as your Lord and saveoir, but have never been baptized,then you need to do so. Even Jesus was baptized by John the Baptist. Read Luke 3:21-22, and Mathew 3:13-17. just find a Christian church that believes in Jesus Christ, the Son of God, crucified and risen and be baptized. Again read Acts 8:26-39.
