"Up to this time, some of you have had faith in 'Jesus Christ' but you have been like precocious children. Your faith has been partially blind and accepting, yet interwoven with much doubt.
Therefore, whatever you needed to be done for you, you depended on 'Jesus' for the work to be accomplished. Whereas, in fact, much of what you believe you have derived directly from 'Jesus' has been your own 'faith in Jesus' made visible in the form of things asked for.
