Question...In , Did Philip Water Baptize The Ethiopian After he told Philip he " Beleived" ?....YES....Did Jesus command John The Baptist to Water Baptize him?
" Yes".
Was Cornelius in and his house Water Baptized by Apostle Peter after he COMMANDED them all to do so? " YES"
Peter never told Cornelius and his family to " Accept the Lord as your personal savior, and you are all saved" nor did Cornelius argue or debate Peter when he COMMANDED them to get Water Baptized.
He obeyed no ifs, ands, or buts
Do ask yourself this...If people In the NT in scriptures never argued or debated this important part of salvation, and God' s word is forever....Why do people want to argue and debate what it plainly tells all of us to do?
I am not speaking against water baptism, but am saying that it is not a prerequisite to salvation. As you will notice in your own example about Cornelius, they had the Holy Spirit before water baptism. Only the saved can receive the Holy Spirit. There are no works that can be done for salvation.
Jesus had to be baptized since our sin was placed upon him.
