what is Holy Spirit

 I've read that Holy Spirit is the manifestation of God's Son.

Jesus beening the Word of God, so can we say that Holy Spirit is the, Power of the Word ?

When we are filled w/ the Holy Ghost, then we truly have the Power to overcome.

As we yield to Him and progress in our faith, does it then come down to us realzing, the

power has been inside of all along?

And please, ..there is now no condemnation for those who are in Christ Jesus. Rom 8:1

Thanks
