Why does God delay to answer prayer?

Consider these thoughts by the Puritan Thomas Watson in his book The Body of Divinity.

1. Because he loves to hear the voice of prayer. ‘The prayer of the upright is his delight.’ Prov 15: 8. You let the musician play a great while ere you throw him down money, because you love to hear his music. Cant 2: 14.
2. God may delay prayer when he will not deny it, that he may humble us. He has spoken to us long in his word to leave our sins, but we would not hear him; therefore he lets us speak to him in prayer and seems not to hear us.
3. He may delay to answer prayer when he will not deny it, because he sees we are not yet fit for the mercy we ask. Perhaps we pray for deliverance when we are not fit for it; our scum is not yet boiled away. We would have God swift to deliver, and we are slow to repent.
4. God may delay to answer prayer, that the mercy we pray for may be more prized, and may be sweeter when it comes. The longer the merchant’s ships stay abroad, the more he rejoices when they come home laden with spices and jewels; therefore be not discouraged, but follow God with prayer. Though God delays, he will not deny. Prayer vincit invincibilem [conquers the invincible], it overcomes the Omnipotent. Hos 12: 4. The Syrians tied their god Hercules fast with a golden chain, that he should not remove. The Lord was held by Moses’ prayer as with a golden chain. ‘Let me alone;’ why, what did Moses? he only prayed. Exod 32:10- 11. Prayer ushers in mercy. Be thy case never so sad, if thou canst but pray thou needest not fear. Psa 10: 17. Therefore give thyself to prayer.

Dear ones. Don’t give up. Persevere in prayer.
