We are filled with the Holy Spirit by faith. How did you become a Christian? By faith. "It is by grace you have been saved, through faith -- and this not from yourselves, it is the gift of God -- not by works, so that no one can boast." "So then, just as you received Christ Jesus as Lord, continue to live in him."Though you are filled with the Holy Spirit by faith and faith alone, it is important to recognize that several factors contribute to preparing your heart for the filling of the Spirit. First, you must desire to live a life that will please the Lord. You have the promise of our Savior, "Blessed are those who hunger and thirst for righteousness, for they will be filled."
