Who are we to twist the words of the bible?

why do people read what the bible says and say "ohh he meant this" or "that was for them not for us" Acts 2:38: go and be baptized every one of you in the name of Jesus Christ for the remission of your sins and ye shall receive the gift of the Holy Spirit. people say "ohh that was for the disciples" "we are not meant to have this Holy Spirit or speak in tongues." but then the Bible says, And the promise is unto YOU and your CHILDREN and unto ALL who are AFAR off. EVEN AS MANY as our Lord God shall call. see, many things are for Christians today we just dont have to desire to seek God
