John 14:6 Jesus said to him, "I am the way, the truth, and the life (Light). No one comes to the Father, except through me.
John 1:4 In Him was life, and that life was the light of men.
Ephesians 2:18 For through Him we both have access to the Father by one Spirit.
Truth is like a "lit" candle. It burns in the darkness and Lights our way. Without oxygen, the flame goes out. But you still have a candle in your hand. You may think you are walking down the path because you possess a candle. But without oxygen, you are bound to stumble, fall and, eventually die.
Like oxygen to a lit candle, the Holy Spirit is to Biblical truth. Biblical principles separated from the Holy Spirit become deception.
