What all this means is difficult to comprehend, but enough appears on its face to lead us to believe that the angels in heaven are deeply interested in our praying, and are sent to tell us the answers to our prayers. Further, it is very clear that some unseen forces or invisible spirits are operating to hinder the answers to our prayers. Who the Prince of Persia was who withstood this great angelic being is not divulged, but enough is revealed to know that there must be a contest in the unseen world about us between those spirits sent to minister to us in answer to our prayers and the devil and his evil spirits who seek to defeat these good spirits. The passage furthermore gives us some intimation as to the cause of delayed answers to prayer. For “three full weeks” Daniel mourned and prayed, and for “one and twenty days” the divinely appointed angel was opposed by the “Prince of the Kingdom of Persia.” Well was it for praying Daniel that he had the courage, fortitude and determination to persist in his praying for three weeks while the fearful conflict between good and bad spirits was going on about him unseen by mortal eyes. Well will it be for us if we do not give up in our praying when God seems not to hear and the answer is not immediate. It takes time to pray, and it takes time to get the answer to prayer. Delays in answering prayer are not denials. Failure to receive an immediate answer is no evidence that God does not hear prayer. It takes not only courage and persistence to pray successfully, but it requires much patience. “Wait on the Lord and be of good courage; and he shall strengthen thy heart; wait, I say, on the Lord.” CHAPTER XI FAITH OF SINNERS IN PRAYER _A certain preacher whose sermons converted many souls received a revelation from God that it was not his sermons or works by all means but the prayers of an illiterate lay brother who sat on the pulpit steps pleading for the success of the sermon. It may be in the all-revealing day so with us. We may believe after laboring long and wearily that all honor belongs to another builder whose prayers were gold, silver, and precious stones, while our sermonizings being apart from prayer are but hay and stubble._--REV. C. H. SPURGEON. One of the peculiar features of prayer as we study the Old Testament on this subject is the faith of unrighteous and back-slidden men in prayer, and the great confidence they had in the prayers of praying men of that day. They knew certain men as men of prayer, who believed in God, who were favored of God and who prayed unto God. They recognized these men as having influence with God in averting wrath and in giving deliverance from evil.
