The Holy Spirit is critical to your life to teach, instruct, and guide you directly. This is a greater blessing than I can convey.

Invite the Holy Spirit to teach you the ways of the Lord just as David requested: 

Show me your ways, O Lord, teach me your paths; guide me in your truth and teach me, for you are God my Savior, and my hope is in you all day long.  – Psalms 25:4-5  (NIV)

This is a blessing that God still honors in our day and age. I know this from firsthand experience, but don’t take my word for it. You can put your trust in the fact that Christ promised that God would: 

But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you. - John 14:26 (NIV)

This was further elaborated on by the Apostle Paul in a letter to the church at Corinth:

The person without the Spirit does not accept the things that come from the Spirit of God but considers them foolishness, and cannot understand them because they are discerned only through the Spirit. — 1 Corinthians 2:14

Only through the Holy Spirit are God’s Word and His truths revealed. The Lord’s divine vastness is not discerned by human understanding

So, this is really, really important. If you take only one thing from me ever, if there’s just one thing I ever say that you remember, let it be this: The Holy Spirit will always be your best instructor in the ways of the Lord in your life and how His Word applies to your life.
