There are people who are critical or doubtful of anything to do with the Holy Spirit because they’re afraid of fraud. Admittedly, fraud has been an issue in all areas of the church, but that is not a reason to dismiss an entire aspect of God.
Jesus taught that the Holy Spirit was sent from God. But the Helper, the Holy Spirit, whom the Father will send in My name… (Jn 14:26) Will you argue with Jesus that the Holy Spirit is not of God? The power of our authority as believers comes from the presence of the Holy Spirit in our lives. We can’t do what we’ve been given to do without Him.
Ironically, the One who can be the greatest source of truth is the Holy Spirit Himself. However, when He the Spirit of truth, has come, He will guide you into all truth. (Jn 16:13) If you are really uncertain that receiving the Holy Spirit is scriptural, then you need to go back and read the scriptures again. Ask God to give you understanding and clarity. Don’t rely on one person’s opinion. You are responsible for your own faith.
Once you make friends with the Holy Spirit, you are connected with God in a way that will cover you with grace and peace. All the fruits of the Spirit are yours forever.
