The Holy Ghost is the third Member of the Holy Trinity- 4 times in the New Testament ( KJV) called the Holy Spirit; 90 times( KJV) called the Holy Ghost.Likely the reason for the different denotations is that the one is His name , the other His wonderful influences in the hearts and lives of His children. AS His born again sons and daughters,our hearts are His garden. He plants there His sweet virtues- Galatians 5:22,23 and cultivates them with urges to our souls and circumstances that will prod us to make decisions for good against evil ( Hebrews 5:14). Sin binds His hand and we must repent and believe daily as He speaks in order to have fellowship with Him.May we listen for Him and respond to His voice as He speaks through our meditation on His Word.
