Eyes receive light. Eyes do not produce light. Imagine how hard it would be to sleep if your eyes produced light. Same with ears; They receive (not produce) sound.
I think that faith is like ears and eyes. Faith is like the organ of the innermost being. It is the organ that receives the things of God. One must see to have faith and revelation is what is beheld. One must hear to have faith, and the Voice of the Shepherd is what is heard.
Thus being receptive, listening, etc. is all that is required when you have ears to hear what God is saying to the willing spirits of those predestined for redemption.
'I, the Lord your God, have commanded all everywhere to repent and come to Me in the Christs name and build Me a church, a church of men, not by men, a church all in all in Christ. One God, one Son, one Church, one name, the only name given by which you must be saved!' ~ God - Volume 3 - 'Worship the Lord Your God as I Am, Not as Men Would Have You Worship'
