Only Believers received the Holy Spirit at Pentecost as is evident in signs and wonders that coincided His arrival. Prior to Pentecost the Holy Spirit did not indwell all Believers. The Father gave us His Holy Spirit as a gift to the Church and as a testimony to who He is. In OT times the Holy Spirit was poured out on some, here and there, but at Pentecost something miraculous occurred and we were made a temple for the Holy Spirit.
I am going to send you what my Father has promised; but stay in the city until you have been clothed with power from on high.” Luke 24:49 NIV
