“I baptize you with water,” John the Baptist said, “but he will baptize you with the Holy Spirit,” Mark 1:8. So what’s the difference between the two baptisms, and does it matter?
It certainly mattered to Paul when he discovered some disciples in Ephesus in Acts 19:1-2, because the big question on Paul’s mind was, “Did you receive the Holy Spirit when you believed?” No, they replied, they’d never “even heard that there is a Holy Spirit,” which made Paul wonder what baptism they’d received instead.
“John’s baptism,” they said, which to Paul was all well and good as a “baptism to repentance,” but far more important was belief in Jesus, verse 4. So they were all baptized again, this time “into the name of the Lord Jesus,” at which point “the Holy Spirit came on them,” verse 5.
But what difference did the Holy Spirit coming on them make? There’s a clue in verse 13. Some Jewish exorcists were using “the name of the Lord Jesus” to try and rid people of evil spirits. But it hadn’t worked (verse 15-16). To have power over evil, the name of Jesus wasn’t enough. More was needed. But what?
A famous sorcerer in Acts 8 knew the answer to that. He’d watched many of his followers being baptized when they heard about “the name of Jesus Christ,” verse 12. He was even baptized himself (verse 15). But when Peter and John arrived, “they prayed for them that they might receive the Holy Spirit, because the Holy Spirit had not yet come upon them; they had simply been baptized into the name of the Lord Jesus,” verses 15-16.
So, again, the name of Jesus wasn’t enough. More was needed, and Simon the sorcerer saw what it was. When he “saw that the Spirit was given at the laying on of the apostles’ hands, he offered them money and said, ‘Give me also this ability so that everyone on whom I lay my hands may receive the Holy Spirit’.”
Simon knew where the power was. It was in the Holy Spirit, and if he could lay his hands on people like the apostles did and that kind of power was released in people, how much more famous Simon could be. He’d watched Philip even cast out evil spirits and heal paralytics (verse 7), so think of the power the Holy Spirit would give him too.
HE knew what difference the Holy Spirit makes. The Spirit has the power to cure anything that ails us. A baptism to repentance doesn’t do that, nor does baptism in the name of Jesus. It’s only by receiving the Spirit AS WELL that power over evil and the damage it has done to us is possible.
