The HolySpirit is the SpiritOfChrist Jesus.
We are SonsOfTheHolySpirit by virtue of the HolySpirit in us. We are expected to do the works that Jesus did.
Despite being virgin born and despite being filled with the HolySpirit, had Jesus not believed who He was and in the power of His HolySpirit in Him, He would never have manifested as Saviour and Lord.
The same applies to you and me. Unless we believe the words that our Lord has spoken over us, the gift within us lies dormant. We remain only potential with the world never seeing SonsOfTheHolySpirit. 1Jn 3:2 Rom 8:19
