Others who are very open and hungry for a touch are not powerfully affected, at least outwardly. If you believe you may have such a barrier, ask God to reveal the nature of it to you. He will be faithful, in His time, to answer such a request. In the meantime, do not assume that it must be a barrier that is keeping you from receiving from God. Actually, God moves upon and woos people closer to Himself who never bring forth the fruit that He intends through these encounters with His grace.
People are free to respond fully, partially, or even ignore such spiritual opportunities.
If it is really the power of the Holy Spirit on these people, then they should not have any control over their responses and behavior. There is a mysterious combination of the divine and human powers surrounding the Spirit's work. Peter knew how to walk and had the power to do so when Jesus invited him out onto the water. The supernatural side of the event was that he didn't sink as he walked. On the front end of welcoming the Spirit's manifest presence, there is more control at our disposal to respond to his activity.
