In my needy life, Lord, my heart is much exercised under the impact made by the words of your holy scripture. All too frequently the poverty of human intelligence has plenty to say, for inquiry employs more words than the discovery of the solution; it takes longer to state a request than to have it granted, and the hand which knocks has more work to do than the hand which receives. We hold on to the promise, which none can make null and void.
‘If God is for us, who can be against us?’ (Rom. 8: 31). ‘Ask and you shall receive, seek and you shall find, knock and the door shall be opened to you. For everyone who asks receives and the door is opened to the one who knocks’ (Matt. 7: 7–8). These are your promises, and when the promise is given by the Truth, who fears to be deceived?
