Once again, you're confusing the two things. Manifestation of the Spirit means those outward miraculous things such as healings, tongues, miracles, prophesy, etc. The Spirit dwells in us upon baptism with no outward, noticeable signs. Our sins are forgiven, we receive the gift of the Holy Ghost, and are added to the body of Christ by the Lord which is his church per verse 47 of Acts 2. This happened to them in biblical times as well as us today, but as mentioned, those who had the apostle's hands laid on them were subject to receiving gifts. Not all however since the scriptures say that prior to the laying on if their hands, the apostles prayed that they MIGHT receive the gifts. So it wasn't automatic to everyone necessarily.
