There isn't anything quite so chilling, quite so disheartening as a man without the Holy Spirit preaching about the Holy Spirit. –Tozer
What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? 1 Corinthians 6:19
The moment a sinner receives the Lord Jesus as Saviour they are filled with the Holy Spirit. The Holy Spirit is given to be our comforter, helper, and guide until Jesus comes again. So how can one that doesn’t have the Spirit living and abiding in them stand to proclaim something they know not of? They can’t and neither can you! You can’t be a witness of something you have never tasted, never seen, or never felt!
Are you saved or are you just trying to tell others about something you have never experienced?
