However, when He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own [authority,] but whatever He hears He will speak; and He will tell you things to come. John 16:13 (NKJV)
You have reliable inward guidance and it’s not a something but He is a Someone.The Holy Spirit is a Divine Guide who has come to live in and with you forever (John 14:16-17) so He may guide you always in all the affairs of life. He is the Spirit of Truth so all His guidance is Truth. His guidance results in freedom because He always guides us in all the ways and principles of God.
