When you look up the meaning in a Dictionary, it says,
noun (in Christianity) the third person of the Trinity; God as spiritually active in the world.
In other words, the holy spirit is God’s power in action, his active force. Let’s see what Bible has to say,
He may be invisible, but very real. He is probably the least understood person. Among the myths and misconnects, He has been described as a force and a ghost, which puts Him down as a replacement God. Often confused with the manifestations and regarded as an incidental figure that appears momentarily. Nothing could be further form the truth.
As Christians, it is vital to know the Spirit, learn to relate and understand how He manifests Himself.
In my book, Eclipse of Timothys, I have attempted to dispel these mistaken concepts.
