I believe it because the holy scriptures say so and I believe them; I guess that means I do not know as one might know a thing through worldly knowledge because worldly knowledge is based on sight and sense but faith comes from hearing the word of Christ (Romans 10:17) and it is the Lord Jesus Christ who said "Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God" (John 3:5) and he also said "He that believeth and is baptised shall be saved" (Mark 16:16) I believe the Lord Jesus Christ and in his gift of the Holy Spirit.
if the apostle were asked this question do you think their reply would be ambiguous like that ? how did they know they were baptized in the holy ghost . we are not baptized in the holy ghost because one one else who is also not baptized i the holy Ghost lays their hand on you and says so. it is God who does it not man .
it is interesting that when a person in the word receives an evil spirit there is manifestation of that spirit and no one has any problem with that and they al say oh that person has a demon or an evil spirit ..
But when it comes to the holy Spirit they think there is no manifstation of his presence ? even though the lord Jesus said you know the wind by the effect it has .. .. well its the same with the holy Spirit ,. when one is baptized in the holy Spirit one
knows it by the tangible evidence .. because the very reason he is baptizing us is to acknowledge our faith in him ... the lord is giving to us the down-payment of himself as evidence to us that he wil also give us the fullness in due time .
if the lord has acknowledge our faith i this manner we can say with absolute assurity of it happening to us and of the presence of the holy Spirit indwelling us due to the tangible experience of it as evidence to us . it is a sign that follows faith .. it is not known by faith . it is known because it follows the faith of the heart .
if we cannot testify of it it is simply because it has not yet taken place .
it is good that you believe the scripture but can you testify if the moment you were baptized in the holy Ghost .. ?the promise is true . but have you received the promise ? can you testify of doing so ?
if not .. that's fine . simply "ask the father " who, the lord Jesus said " will give ... and when he does .. you will know .
i will add so that some do not be misled . the baptism of the Holy Ghost is not earned and is not a qualification. his presence within is not an automatic change of character ..one must continue to walk in obedience to the lord and be changed .the baptism of the holy Spirit and his anointing upon a person does not automatically validate what that person does -if anything it makes them even more accountable to God . it is ,i believe for this reason that when folks go astray they are dealt with more harshly ,exposed and publicly humiliated for doing so .
the isralites knew of the promised land .. but the knowing of it and the receiving of it are two very different things .
