What can I say to convince you?

So far as you disbelieve, so far you lose your power to be the conductor of the love of God to your fellow beings.

The secret of all power to help others is for you to be just the passive instrument in God's hands to teach, show and prove what he says. 

When self or unbelief comes in, there is weakness and loss of power—the darkness of material things shuts you out from God and His Truth.
