Pilot light only, or fully burning?

I am reminded of your sincere faith, which first dwelt in your grandmother Lois and your mother Eunice, and I am convinced is in you as well. For this reason I remind you to fan into flame the gift of God, which is in you through the laying on of my hands. For God has not given us a spirit of timidity, but of power, love, and self-control - 2 Timothy 1:5-7

Alphausa.org has great materials to help people understand the Christian faith. This is from the lesson "How can I be filled with the Holy Spirit?"

We want each person to experience the love of God and be filled with the Holy Spirit (Ephesians 5:18), to know they belong to Christ (Romans 8:9).
As we know some people are longing (Acts 2:2–4), receptive (Acts 8:14–17), or hostile (Acts 9:17–20) - we ask God to break the barriers and let faith take root and be fruitful. Let's pray against the common barriers, pray for them to be removed (doubt, fear, and inadequacy Luke 11:9-13).
