Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: for every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. Matthew 7:7-8
Here is a precept in three words to the same purport, Ask, Seek, Knock (v. 7 ); that is, in one word, “Pray; pray often; pray with sincerity and seriousness; pray, and pray again; make conscience of prayer, and be constant in it; make a business of prayer, and be earnest in it. Ask, as a beggar asks alms.” Those that would be rich in grace, must betake themselves to the poor trade of begging, and they shall find it a thriving trade. “Ask; represent your wants and burthens to God, and refer yourselves to him for support and supply, according to his promise. Ask as a traveller asks the way; to pray is to enquire of God, Eze. 36: 37 . Seek, as for a thing of value that we have lost, or as the merchantman that seeks goodly pearls. Seek by prayer, Dan. 9: 3 . Knock, as he that desires to enter into the house knocks at the door.” We would be admitted to converse with God, would be taken into his love, and favour, and kingdom; sin has shut and barred the door against us; by prayer, we knock; Lord, Lord, open to us.
