If you read Mathew 28 :19 ,He said in the name nt names,but mentioned three things Father,Son and Holyghost,nw the question ,is fathe aname,no father is nt aname but title that father must have aname,iam son but my name is nt son,wat dd Jesus meant ? On Luke 24:47-49 they wr told that remission of sins and repentance be preached in His name starting frm Jerusalem,and wr told to wait until they are endued with the power frm above,they wr nt told to go to theology school but to wait upon the holyspirit,becoz John 14:26 told us that this holyghost is the teacher ,now on acts 2 is when they received the holyghost,there wr so many people frm different nations,let me say that nw it was the holyspirit in control,nw when Peter with full of holyghost taught people who wr there until the holyghost remind them on Acts 2:36, therefore let the house of Israel as*uredly ,that God hath made that same Jesus whom you crucified ,both Lord and Christ.These people wr people who crucified the Lord thinking that they were doing service to God,when they heard this it pained them until they asked wat to do.Acts 2:38-41.repent and they wr baptised in the name of the Lord Jesus.
