One without faith would never have acted thus, but would have concluded: It is of no use to present my request before Him; I am in the clutches of the devil beyond all hope; let His own people come to Him; them will He hear, but not me. Whoever has no faith is utterly unable to pray. The woman is not vexed with doubts as to her privilege of coming to Christ: she does not spend the time in debating the question, whether she dare come or not; she simply starts upon her way and comes. It is surely a severe and dangerous affliction when the devil prompts the heart to despair of the mercy of God, to refuse to pray to Him, yea, rather to be ready to curse Him, and to think that all is lost and damnation sure. Such wicked thoughts deter an inexperienced heart from prayer and throw it into despondency. This story is therefore of great value for us, and written on our account, so that we might know how to meet the enemy when he comes and says:

“You are no Christian, your prayer is in vain.” Mind not such insinuations, but answer boldly: I care not who I am. I know that I am a sinner, but I also know that Christ my Lord is holy, ever just and merciful. Therefore I will call unto Him without hesitation and think of nothing besides; I have no time to debate, whether I am one of the chosen or not. This much I know: I need help, and on that account I come, humbly seeking it. If we are thus disposed in mind, we follow the example of our Gospel aright. The woman was a heathen, and, aware of that, she had to conclude that she did not belong to the chosen people; she swallows, however, contentedly this big and bitter morsel, still praying unto Christ with much earnestness. Go and do likewise; say: O Lord, here I come, in want of everything. Give me what I need through Thy Son, my Lord and Savior Jesus Christ! Such a struggle of faith, and wonderful exhibition of its nature, is manifested in this heathen woman.  (Luther’s House Postil, Sermon for Reminiscere, Volume 1, p. 266-267)

This struggle is portrayed in the woman of our text. The person and all attending circumstances are of the most unpromising kind. The first unfavorable circumstance is the fact that the woman is of heathen birth, no child of Abraham, nor of his lineage; and therefore, being a stranger, she has no right to ask any favors here. This she knew, and it would have been no wonder if this fact had prevented her coming. She might easily have been led to think: Why shall I go, and what shall I ask? It is all in vain. I am a heathen and foreign woman; He is a Jew, and one sent unto the Jews. I very much doubt whether we would overcome such obstacles as this; we would succumb to them, and give up our prayer. It is no trifling matter when conscience appears with its charges and tells us: What are you about? You have not the right to pray, as you are not Christ’s disciple; let Peter and Paul pray to God; these He will hear, but not you. You have no faith; perhaps you are not one of the elect, and surely unworthy to come before God with your petitions. With thoughts like these the devil can bring us to despair; for indeed the obstacles are great. When thus perplexed let us look for encouragement upon this woman, and learn to conduct ourselves as she did.

The difficulties in the way do not appall her; she keeps only in view the object of her coming, and forgets that she is a heathen and He a Jew. Her confidence and hope in Christ are so great that she never doubts His condescension. Her faith cancels the fact that she is a heathen.
