The True Meaning of Baptism in Jesus Name

All scripture references, unless otherwise noted, are from the King James Version of the Holy Bible.
Is baptism necessary? Yes if you want to do what the Lord Jesus said. In Mark 16:16 the Lord said, "He that believeth and is baptized shall be saved; but he that believeth not shall be damned." It sounds to me like you won't be saved without believing or being baptized. The Bible tells of when Philip met the Ethiopian eunuch and preached Jesus Christ to him. In Acts 8:36-38 gives the account as follows, "And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized?  And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God. And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him." Philip said to the eunuch, "if you  believe you may." The eunuch's response was "I believe that Jesus Christ is the Son of God." He qualified and he was baptized!

Is the name of Jesus necessary? Yes because the Bible says in Acts 4:12,  "Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved." But what about Matthew 28:19 which instructs the early believers to, "Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost..." I would note that no one was baptized then and there, but when they went they baptized people in the name of Jesus.

Some have said that baptism has nothing to do with salvation. I would argue that based on at least the two previous examples that they are wrong. In fact the Bible says in 1st Peter 3:20b-21 that Noah and his family, "...that is, eight souls were saved by water. The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ..." No, not the idea of baptismal regeneration but in the answer we give as the eunuch gave to Philip. (See above) Friend if you haven't repented of your sins and believed that the Lord Jesus died for you and resurrected from the dead, you are not qualified to be saved. To be saved according to the Bible you must believe and be baptized, just like Jesus said!
