"God does not say, Ask once, and you shall receive. He bids us ask. Unwearyingly persist in prayer. The persistent asking brings the petitioner into a more earnest attitude, and gives him an increased desire to receive the things for which he asks. Christ said to Martha at the grave of Lazarus, “If thou wouldest believe, thou shouldest see the glory of God.” John 11:40 . COL 145.3"
"Jesus saith unto her, Said I not unto thee, that, if thou wouldest believe, thou shouldest see the glory of God?"
Ellen White directly references John 11:40 in this passage.
