"Some would even go as far as to say that it is sinful to pray such a prayer now (Luke 11:11-13). Does not Romans 8:9 tell us that "If any man have not the Spirit of God he is none of His?". I reply if you are going to take that dispensational view of this verse then why do you not take a similar view of every verse in the Gospels?
The Sermon on the Mount they say has got nothing to do with Christians ... If such is the case the position obviously becomes ridiculous. It is certain that these verses apply to us as much as they did to the people whom our Lord first uttered them and we are to ask God as our Father for the Holy Spirit today as then".
