I'll Quote Macarthur for context. on these passages in Acts. If you can give me your thoughts on this.
" the believers in Samaria who were converted under the ministry of Philip had to wait a short while to receive the baptism with the Holy Spirit, until Peter and John came up to Samaria and laid hands on the converts (Acts 8:17). In that unique transitional situation as the Church was beginning, those particular believers had to wait for the Holy Spirit, but they were not told to seek Him. The purpose for that exception was to demonstrate to the apostles, and to bring word back to the Jewish believers in general, that the same Holy Spirit baptized and filled Samaritan believers as baptized and filled Jewish believers--just a short while later Peter and a few other Jewish Christians were sent to witness to Cornelius and his household in order to be convinced that the gospel was for all men and to see that "the Holy Spirit had been poured out on the Gentiles also"(Acts 10:44-45). Those special transitional events did not represent the norm, as our present text makes clear, but were given to indicate to all that the body was one"....
"Why did the Samaritans (and later the Gentiles) have to wait for the apostles before receiving the Spirit? For centuries, the Samaritans and the Jews had been bitter rivals. If the Samaritans had received the Spirit independent of the Jerusalem, that rift would have been perpetuated. There could well have been two separate churches, a Jewish church and a Samaritan church. But God had designed one church, in which "there is neither Jew nor Greek, there is neither slave nor free man, there is neither male nor female," but "all are one in Christ Jesus" (Gal. 3:2.)...
By delaying the Spirit's coming until Peter and John arrived, God preserved the unity of the church. The apostles needed to see for themselves, and give firsthand testimony to the Jerusalem church, that the Spirit came upon the Samaritans. The Samaritans also needed to learn that they were subject to apostolic authority. The Jewish believers and Samaritans were thus linked together in one body....
Today, believers receive the Spirit at salvation (cf.1 Cor. 12:13). There was no need for delay after Jews, Gentiles, Samaritans, and Old Testament saints were already included in the church. (Macarthur)

"Being filled with the spirit must be distinguished from being baptized with the spirit. The apostle Paul carefully defines the baptism with the spirit as that act of Christ by which He places believers into His body (Romans 6:4-6; 1 Corinthians 12:13; Galatians 3:27). In contrast to much errant teaching today, the New Testament nowhere commands believers to seek the baptism with the Holy Spirit. It is a sovereign, single, unrepeatable act on Gods part, and is no more an experience than are its companions justification and adoption. Although some wrongly view the baptism with the Spirit as the initiation into the ranks of the spiritual elite, nothing could be further from the truth. The purpose of the baptism with the spirit is not to divide the body of Christ, but to unify it. As Paul wrote to the Corinthians, through the baptism with the Spirit "we were all baptized into one body" (1 Corinthians 12:13; cf. Galatians 3:26-27; Ephesians 4:4-6)
Unlike the baptism with the Spirit, being filled with the Spirit is an experience and should be continuous. Although filled initially on the day of Pentecost, Peter was filled again in Acts 4:8. Many of the same people filled with the Spirit in Acts 2 were filled again in Acts 4:31. Acts 6:5 describes Stephen as a man "full of faith and the Holy Spirit," yet Acts 7:55 records his being filled again. Paul was filled with the Spirit in Acts 9:17 and again in Acts 13:9.
While there is no command in scripture to be baptized with the Spirit, believers are commanded to be filled with the Spirit (Ephesians 5:18 ). The grammatical construction of that passage indicates believers are to be continuously being filled with the Spirit. Those who would be filled with the Spirit must first empty themselves. That involves confession of sin and dying to selfishness and self will. To be filled with the Holy Spirit is to consciously practice the presence of the Lord Jesus Christ and to have a mind saturated with the Word of God. Colossians 3:16-25 delineates the results of "letting the word of Christ richly dwell" in us. They are the same ones that result from the filling of the Spirit (Ephesians 5:19-33). As believers yield the moment by moment decisions of life to His control, they "walk by the Spirit" (Galatians 5:16). The baptism of the Spirit grants the power that the filling with the Spirit unleashes." (Macarthur)
