So it is with every other one of God's requirements. All His gifts are promised on condition of obedience. God has a heaven full of blessings for those who will co-operate with Him. All who obey Him may with confidence claim the fulfillment of His promises.
But we must show a firm, undeviating trust in God. Often He delays to answer us in order to try our faith or test the genuineness of our desire. Having asked according to His word, we should believe His promise and press our petitions with a determination that will not be denied.
God does not say, Ask once, and you shall receive. He bids us ask. Unwearyingly persist in prayer. The persistent asking brings the petitioner into a more earnest attitude, and gives him an increased desire to receive the things for which he asks. COL 145
