We are having a bit of disagreement in our Bible Study. In John 20:22, Jesus blew unto his disciples with the Holy Spirit. In Acts 2:4 his disciples received the Holy Spirit at Pentecost. Is this the same thing, though it happens in different times and places?
The disciples “received” the Holy Spirit on the night of the Lord’s resurrection (John 20:22). Since then every believer has received the Holy Spirit upon hearing the gospel and believing it. Ephesians 1:13-14 and 2 Cor. 1:21-22 both confirm this.
At Pentecost the Holy Spirit “came upon” the disciples in power. The difference is that the first instance demonstrates the Holy Spirit being sealed within us, and the second one shows Him working miraculously through us. All believers can experience both.
That’s not to say that all believers will speak in different languages like the disciples did (Acts 2:4), but all believers can experience the Holy Spirit working miraculously through us. He gives spiritual gifts to each of us as He determines for the good of the body (1 Cor. 12:7-11).
