God promised, Isaiah 58:9, to answer them when they called; here he promiseth to be so ready to answer, as to answer the words as soon as they should be formed in their hearts, before they should get them out of their lips, Psalms 32:5 Daniel 10:12; yea, while they were speaking, Daniel 9:20,23 Ac 10:44. Nor doth God say only they shall have the things they would have, (for so wicked men may sometimes have from the bountiful hand of Divine Providence,) but they shall have them as an answer or return unto their prayers.
