My friend, once a person has received the gift of the Holy Ghost, the inspiration is there. Some people read the Bible and understand things without realizing it is God talking to their heart by the Holy Ghost that has given them any real understanding at all:
What power is it that the Holy Ghost gives to us?
"But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth." Acts 1:8
To be witnesses? How can we be witnesses? By the power of God through the Holy Ghost.
You use the word, inspiration, as if it was some special revelation and it certainly is... to the person to whom God is making the revelation. Every person who had been drawn to God has received a revelation, an inspiration, but the end is not yet.
Some people or groups [this means churches as men call them] may believe that they have got all that God has to say through the scriptures already down pat in their heart.
But they do not.
God is unlimited.
He has given people a portion, but that does not have to be the end. It is only the end if we have stopped moving spiritually. If we have then eventually we will die.
To stand still indefinitely is to stagnate. God's people who are to live forever with Him are not stagnate, but Alive!
