2. The covenant-blessings which he has secured to them and theirs, v. 3, 4. (1.) Those that are sensible of their spiritual wants, and the insufficiency of the creature to supply them, shall have abundant satisfaction in God: I will pour water upon him that is thirsty, that thirsts after righteousness; he shall be filled. Water shall be poured out to those who truly desire spiritual blessings above all the delights of sense. (2.) Those that are barren as the dry ground shall be watered with the grace of God, with floods of that grace, and God will himself give the increase. If the ground be ever so dry, God has floods of grace to water it with. (3.) The water God will pour out is his Spirit (John vii. 39), which God will pour out without measure upon the seed, that is, Christ (Gal. iii. 16), and by measure upon all the seed of the faithful, upon all the praying wrestling seed of Jacob, Luke xi. 13. This is the great New-Testament promise, that God, having sent his servant Christ, and upheld him, will send his Spirit to uphold us. (4.) This gift of the Holy Ghost is the great blessing God had reserved the plentiful effusion of for the latter days: I will pour my Spirit, that is, my blessing; for where God gives his Spirit he will give all other blessings. (5.) This is reserved for the seed and offspring of the church; for so the covenant of grace runs: I will be a God to thee and to thy seed. To all who are thus made to partake of the privileges of adoption God will give the spirit of adoption. (6.) Hereby there shall be a great increase of the church. Thus it shall be spread to distant places. Thus it shall be propagated and perpetuated to after-times: They shall spring up and grow as fast as willows by the watercourses, and in every thing that is virtuous and praiseworthy shall be eminent and excel all about them, as the willows overtop the grass among which they grow, v. 4. Note, It is a great happiness to the church, and a great pleasure to good men, to see the rising generation hopeful and promising. And it will be so if God pour his Spirit upon them, that blessing, that blessing of blessings.
