We are all beggars in our hearts–beggars in need of the Bread of Life. We have been given fullness in Christ, but though we have our dear Jesus, we never lose our need of Him. We are like beggars–and in this life, God gives us perpetual need so that we will come hungrily to Him for satisfaction. May we live on this side of glory as persistent widows and salivating beggars who run to God for provision of every need and desire–and may we live expectantly as we trust that He has and will meet us with mercy and grace in our time of need.
Luke 18:1-8 “And he told them a parable to the effect that they ought always to pray and not lose heart. He said, “In a certain city there was a judge who neither feared God nor respected man. And there was a widow in that city who kept coming to him and saying, ‘Give me justice against my adversary.’ For a while he refused, but afterward he said to himself, ‘Though I neither fear God nor respect man, yet because this widow keeps bothering me, I will give her justice, so that she will not beat me down by her continual coming.’” And the Lord said, “Hear what the unrighteous judge says. And will not God give justice to his elect, who cry to him day and night? Will he delay long over them? I tell you, he will give justice to them speedily. Nevertheless, when the Son of Man comes, will he find faith on earth?”
“It is very apparent from the Word of God that he often tries the faith and patience of his people, when they are crying to him for some great and important mercy, by withholding the mercy sought for a season; and not only so, but at first he may cause an increase of dark appearances. And yet he, without fail, at last prospers those who continue urgently in prayer with all perseverance and ‘will not let him go except he blesses.’” 
Lord, teach us to pray and to trust you with everything that we need and desire. Let us be faithful widows and fulfilled beggars.
