I felt I had to write this blog because I have been emphasizing Spirit or the Holy Spirit in my writings or talk that anybody can claim they heard from the Spirit and then nobody can question them or me. How do we know the Spirit is True or Holy ? I will suggest the following. Since God is one in three Persons, the Father, the Son, and the Holy Spirit, I believe as the Scriptures (Bible) says they agree with one another. So the Holy Spirit agrees with the Father and the Son, and how do we know that ? Other Bible verse will have to agree with another Bible verse or more.
Briefly, I have to admit establishing Truth is not easy. But for me I will have to rely on the Lord Jesus because He is Truth, I will also refer to the Bible by study and meditating which includes prayer. I will also make sure that my feeling or desire do not interfere with Truth, by that I mean that I do not say that something is true because I wanted it to be true. Some says the Holy Spirit will give one peace, so I believe that is another telltale.
I probably need to study some more, meanwhile Rejoice in the Lord always.
