18. No man hath seen God
The invisible God has been revealed in Christ. The Fourth Gospel makes considerable play upon the idea of ‘seeing’ with the natural eye (or reason) and ‘seeing’ with the eye of faith; e.g. John 9.37-41; 14.9; 20.29. St John denies that ‘seeing is believing’; he would say rather that believing is seeing.
