Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. For everyone who asks receives; the one who seeks finds; and to the one who knocks, the door will be opened. Matthew 7:7-8
“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 burdens to God, and refer yourselves to him for support and supply, according to his promise [in Matthew 7:7-8].”
Matthew Henry, Commentary on the Whole Bible, notes on Matthew 7:7-11.
