Is There a Difference Between the Holy Ghost and Holy Spirit?
Romans 5:5 - And hope maketh not ashamed; because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us.
Is there a difference between the Holy Ghost and the Holy Spirit?
No, there is no difference between the Holy Ghost and the Holy Spirit. The Holy Ghost and Holy Spirit are one and the same Spirit of God. These two terms are used interchangeably to refer to the same
"Spirit of God." For example:
John 1:33 And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost.
The same Holy Spirit that descended and landed on Jesus at His Baptism is the same Holy Ghost that Jesus baptizes you with.
John 7:39 (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet [given]; because that Jesus was not yet glorified.)
The same Holy Spirit that one would receive if they believed in Jesus is the same Holy Ghost that one would be given at Pentecost. And that did happen:
Acts 2:4 And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
The same Holy Ghost that they were filled with is the same Holy Spirit that gave them the power to speak in tongues.
1 Cor. 12:3 Wherefore I give you to understand, that no man speaking by the Spirit of God calleth Jesus accursed: and [that] no man can say that Jesus is the Lord, but by the Holy Ghost.
The same Holy Spirit that one speaks by, which does not allow them to curse Jesus, is the same Holy Ghost that one needs in order to proclaim Jesus as Lord.
And finally, just as your body is the temple of the Holy Ghost (1 Cor. 6:19), so your body is the temple of God (2 Cor. 6:16), where the Holy Spirit dwells (1 Cor. 3:16), for God is Spirit (John 4:24).
There is more, but let this suffice.
