Snap!!!!There is a difference between vain repetition and asking repeatedly. Jesus did not only ask one time, he asked three times. Again, in the words of our Lord, here is an example he gave us for prayer...
18 Now He was telling them a parable to show that at all times they ought to pray and not to lose heart, 2 saying, "There was in a certain city a judge who did not fear God, and did not respect man. 3 "And there was a widow in that city, and she kept coming to him, saying, 'Give me legal protection from my opponent.' 4 "And for a while he was unwilling; but afterward he said to himself, 'Even though I do not fear God nor respect man, 5 yet because this widow bothers me, I will give her legal protection, lest by continually coming she wear me out.' " 6 And the Lord said, "Hear what the unrighteous judge said; 7 now shall not God bring about justice for His elect, who cry to Him day and night, and will He delay long over them? 8 "I tell you that He will bring about justice for them speedily. However, when the Son of Man comes, will He find faith on the earth?"
We see here that God's elect never stop praying for justice but it is a repeated cry, day and night. Repetitious for sure, but certainly not vain.
Hence my last post.
