A question
Read in the Acts of the Apostles, in chapter 8, starting at verse 15, and through to verse 17. Philip had evangelised a town in Samaria. The people (many) had become Christians. But they hadn't received the Holy Spirit. Only when Peter and John arrived were these people given the Holy Spirit.

Let me say this again - black and white. Some people became Christians. Some days later, they received the Holy Spirit. It is possible to be a Christian, and not to have received the Holy Spirit.

I simply daren't apply this to myself, but the inference is clear.
