Yes, this is where the spiritual gift of "discerning of spirits" (1 Cor 12:10) is highly recommended.
But, first comes the baptism with the Holy Spirit.
Whomever sincerely desires this, trust in Matt 7:7-11.
Those numbers are recommended in Vegas also.
The sinner is baptized in the Holy Spirit the moment he accepts Christ!
Matt. 7:7-11 has nothing to do with being baptized in the Holy Spirit.
Acts 2:38..................
"Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost."
Barnes' says......
"Clearly then we can see that true repentance is the only thing in such a state of mind that can give any relief. An ingenuous confession of sin, a solemn purpose to forsake it, and a true hatred of it, is the only thing that can give the mind composure. Such is the constitution of the mind that nothing else will furnish relief. But the moment we are willing to make an open confession of guilt, the mind is delivered of its burden, and the convicted soul finds peace".
Clark says........
"Ye shall receive the gift of the Holy Ghost - If ye faithfully use the sign, ye shall get the substance. Receive the baptism, in reference to the removal of sins, and ye shall receive the Holy Ghost, by whose agency alone the efficacy of the blood of the covenant is applied, and by whose refining power the heart is purified. It was by being baptized in the name of Christ that men took upon themselves the profession of Christianity; and it was in consequence of this that the disciples of Christ were called Christians."
