These are very sweet promises, both in a temporal, and in a spiritual sense; and all ratified, and confirmed, to the believer, in the charter of grace. When the Lord hath brought sinners into a state of salvation, all the nether spring blessings, and the upper spring mercies, both pour in upon the soul. The figure here made use of, in that of God's hearing the heavens, and they hearing the earth, is very beautiful. In times of drought and famine, the earth in vain looks to the heavens for their beneficial influences, if the Lord shuts them up. But when the Lord acts upon the heavens, and the heavens upon the earth; then there will be showers of blessings', the corn, and the wine, and the oil, shall abound, and the people of Jezreel shall be filled with plenty. The same holds good in grace. When the dry and famished souls of poor sinners are savingly brought acquainted with God's rich mercy in Christ, their heaven is no longer to them iron, and the earth brass, but, the Lord hears and answers the intercession of his dear Son; and while prayers are going up, blessings are coming down; and the Lord becomes gracious to his people. Such, and so great, is the wonderful change brought by sovereign, free, and unmerited grace!
