Christ reminds her of his affirmation. ‘Said I not unto thee, that, if thou wouldest believe, thou shouldest see the glory of God?’ Some people say that he is referring to what he said to her in verse 26 and verse 27.
And he insists so of us too. I come back to all our trials and tribulations, and so on. Are we going to get relief from the Lord? Will he answer our prayers, will he intervene in our circumstances, will he help us? If we believe in the resurrection, and the life – that Christ is those things – then he will deal with us, in his great wisdom.
