Matt 3:5; Then Jerusalem, all Judea, and all the region around the Jordan went out to him
Matt 3:6; and were baptized by him in the Jordan, confessing their sins.
Matt 3:7; But when he saw many of the Pharisees and Sadducees coming to his baptism, he said to them, "Brood of vipers! Who warned you to flee from the wrath to come?
Matt 3:8; Therefore bear fruits worthy of repentance,
It seems everyone in the region was being baptized, and confessing their sins. Baptism isn't really a sign that you are saved nearly as much as you have repented.
If you haven't repented, you aren't ready to be baptized.
Acts 19:4; Then Paul said, "John indeed baptized with a baptism of repentance, saying to the people that they should believe on Him who would come after him, that is, on Christ Jesus."
Acts 13:24; after John had first preached, before His coming, the baptism of repentance to all the people of Israel.
It seems many churches to day are down-playing baptism, some say it isn't required. Often the thief on the cross is used as an example. But the thief didn't have the Holy Spirit either.
He died before Jesus ascended to Heaven and sprinkled His blood on the mercy seat in the tabernacle in Heaven. The Thief was under the old covenant.
Some churches go so far as to say it's just an Earthly ceremony made up by men. But of course that isn't what the Bible says.
Matt 21:25; The baptism of John—where was it from? From heaven or from men?" And they reasoned among themselves, saying, "If we say, 'From heaven,' He will say to us, 'Why then did you not believe him?'
Mark 11:30; The baptism of John—was it from heaven or from men? Answer Me."
Luke 20:4; The baptism of John—was it from heaven or from men?"
Of course Jesus Himself was baptized as our example. If you're a Christian... (a follower of Christ)... then you follow Jesus, you do the things He did. What was one of the first things He did?
Matt 3:13; Then Jesus came from Galilee to John at the Jordan to be baptized by him.
Matt 3:14; And John tried to prevent Him, saying, "I need to be baptized by You, and are You coming to me?"
Matt 3:15; But Jesus answered and said to him, "Permit it to be so now, for thus it is fitting for us to fulfill all righteousness." Then he allowed Him.
Matt 3:16; When He had been baptized, Jesus came up immediately from the water; and behold, the heavens were opened to Him, and He saw the Spirit of God descending like a dove and alighting upon Him.
Mark 1:9; It came to pass in those days that Jesus came from Nazareth of Galilee, and was baptized by John in the Jordan.
Mark 1:10; And immediately, coming up from the water, He saw the heavens parting and the Spirit descending upon Him like a dove.
Luke 3:21; When all the people were baptized, it came to pass that Jesus also was baptized; and while He prayed, the heaven was opened.
John 1:31; I did not know Him; but that He should be revealed to Israel, therefore I came baptizing with water."
John 1:32; And John bore witness, saying, "I saw the Spirit descending from heaven like a dove, and He remained upon Him.
John 1:33; I did not know Him, but He who sent me to baptize with water said to me, 'Upon whom you see the Spirit descending, and remaining on Him, this is He who baptizes with the Holy Spirit.'
Apollos was another who believed in baptism. He didn't understand everything yet, but he understood baptism.
Acts 18:24; Now a certain Jew named Apollos, born at Alexandria, an eloquent man and mighty in the Scriptures, came to Ephesus.
Acts 18:25; This man had been instructed in the way of the Lord; and being fervent in spirit, he spoke and taught accurately the things of the Lord, though he knew only the baptism of John.
Acts 18:26; So he began to speak boldly in the synagogue. When Aquila and Priscilla heard him, they took him aside and explained to him the way of God more accurately.
It's interesting John didn't know who Jesus was until He was baptized in water. In verse 33 John says ... "He who sent me to baptize"... who was this "He". It wasn't Jesus.
So then.. was John's baptism from men or from heaven?
It's also interesting that Jesus's ministry started with when He was baptized.
Acts 1:22; beginning from the baptism of John to that day when He was taken up from us, one of these must become a witness with us of His resurrection."
