The necessity of praying with perseverance is the secret of all spiritual life. What a blessing to be able to ask the Lord for such and such a grace until He gives it, knowing with certainty that it is His will to answer prayer, but what a mystery for us in the call to persevere in prayer, to knock in faith at His door, to remind Him of His promises, and to do so without wearying until He arises and grants us our petition! Is not the assurance that our prayer can obtain from the Lord that which He would not otherwise give the evident proof that man has been created in the image of God, that he is His friend, that he is His fellow worker, and that the believers who together form the Body of Christ participate in this manner in His intercessory work? It is to Christ’s intercession that the Father responds, and to which He grants His divine favors.
More than once the Bible explains to us the need for persevering prayer. There are many grounds, the chief of which is the justice of God. God has declared that sin must bear its consequences; sin therefore has rights over a world which welcomes and remains enslaved by it. When the child of God seeks to quit this order of things, it is necessary that the justice of God should consent to this; time therefore is needed that the privileges which Christ has procured for the believers should weigh before God’s tribunal. Besides this, the opposition of Satan, who always seeks to prevent the answer to prayer, is a reason for it (Dan. 10:12, 13). The only means by which this unseen enemy can be conquered is faith. Standing firmly on the promises of God, faith refuses to yield, and continues to pray and wait for the answer, even when it is delayed, knowing that the victory is sure (Eph. 6:12—18).
Finally, perseverance in prayer is needful for ourselves. Delay in the answer is intended to prove and strengthen our faith; it ought to develop in us the steadfast will which will no longer let go the promises of God, but which renounces its own side of things to trust in God alone. It is then that God, seeing our faith, finds us ready to receive His favor and grants it to us. He will avenge speedily, even though He tarry. Yes, notwithstanding all the needful delays, He will not make us wait a moment too long. If we cry unto Hun day and night, He will avenge us speedily.
This perseverance in prayer will become easy to us as soon as we fully understand what faith is. Jesus teaches us in these words, “All things whatsoever ye shall ask in prayer, believing, ye shall receive” (Matt. 21:22). When the Word of God authorizes us to ask anything, we ought at once to believe that we receive it. God gives it to us; this we know by faith, and we can say between God and us that we have received it, although it might be only later that we are permitted to realize the effects here on earth. It is before having seen or experienced anything whatsoever that faith rejoices in having received, perseveres in praying, and waits until the answer is manifest. But even after having believed that we are heard, it is good to persevere until it has become an accomplished fact.
This is of great importance in obtaining divine healing. Sometimes, it is true, the healing is immediate and complete; but it may happen that we have to wait, even when a sick person has been able to ask for it in faith. Sometimes also the first symptoms of healing are immediately manifest; but afterwards the progress is slow, and interrupted by times when it is arrested or when the evil returns. In such cases it is important for both the sick person and those who pray with him to believe in the efficacy of persevering prayer, even though they may not understand the mystery of it. That which God appears at first to refuse, He grants later to the prayer of the Canaanitish woman, to the prayer of the “widow,” to that of the friend who knocks at midnight (Matt. 15:22; Luke 18: 3; 11: 5). Without regarding either change or answer, the faith which is grounded on the Word of God, and which continues to pray with importunity, ends by gaining the victory. “Shall not God avenge his own elect which cry day and night unto him, though he bear long with them? I tell you he will avenge them speedily.” God knows how to delay all the time which is necessary, and nevertheless to act speedily without waiting more than is needful. The same two things should belong to our faith. Let us lay hold with a holy promptitude of the grace which is promised us, as if we had already received it; let us await with untiring patience the answer which is slow to come. Such faith belongs to living in Him. It is in order to produce in us this faith that sickness is sent to us, and that the healing is granted to us, for such faith above all glorifies God.
