Psalms 67:6

[Then] shall the earth yield her increase
Not literally the land of Israel, as in some copies of the Targum, and as Kimchi interprets it; see ( Leviticus 26:3 Leviticus 26:4 ) ; but mystically and spiritually the church of God in the times of the Messiah, ( Ezekiel 34:23-27 ) ; the word of God preached in the world is the seed sown in it; converts to Christ are the increase or fruit of it; and the church is God's husbandry, where it is yielded or brought forth; and this increase is of God, and is owing to the efficacy of his grace attending the ministration of the word, ( 1 Corinthians 3:6 ) ; it had its accomplishment in part in the first times of the Gospel, when it was preached by the apostles throughout the earth, and brought forth fruit everywhere, ( Colossians 1:5 Colossians 1:6 ) ; and has been fulfilling more or less ever since, and will appear more abundantly in the latter day; a large increase and a plentiful harvest of souls shall be brought in, both Jews and Gentiles: or this may be understood of the fruitfulness of believers in Christ, who may be called "earth", because of their common original from the earth with the rest of mankind; because they are inhabitants of the earth; and because they have earthly as well as heavenly principles in them; but more especially because they are the good ground on whom the seed of the word falls and becomes fruitful; or are the earth which drinks in the rain of the Gospel, and of grace, and brings forth fruit meet for them, by whom it is dressed, and receives blessing of God, ( Matthew 13:23 ) ( Hebrews 6:7 ) ; these yield the fruits of the Spirit, increase in grace, and abound in the exercise of it; bring forth fruits meet for repentance, being filled with the fruits of righteousness by Christ; for the increase and fruit yielded by them are owing to the grace of God, to their grafting into Christ the vine, and to the influence of the blessed Spirit. Some of the ancients understand this of the incarnation of Christ; see ( Psalms 85:11 ) ( Isaiah 45:8 ) ; then "the earth" is the Virgin Mary, who was, as to her original, of the earth, earthly; of whose earthly substance Christ took flesh, and is called the fruit of her womb; yea, the fruit of the earth, ( Luke 1:42 ) ( Isaiah 4:2 ) ; for though he is the Lord from heaven, as to his divine nature, and came down from thence, not by change of place, but by assumption of nature; yet, as to his human nature, he was made of a woman, and is the seed of the woman, the promised seed, in whom all nations of the earth were to be blessed; and it here follows:

[and] God, [even] our own God, shall bless us;
not as the God of nature and providence only; but as the God of grace, as a covenant God in Christ, in which sense he is peculiarly his people's own God, so as he is not others; and as such he blesses them with all spiritual blessings in Christ: or the repetition of the word "God", with the affix "our own", may denote the certainty of the divine blessing, the assurance had of it, and the great affection of the persons that express it: and some think, because the word is repeated three times in this verse and ( Psalms 68:7 ) , respect is had to the trinity of Persons in the Godhead; God the Father blesses his people in Christ with the blessings of justification, pardon, adoption, and eternal life: the Son, who is Immanuel, God with us, God in our nature, our own God, God manifest in the flesh; he blesses with the same blessings of grace, peace, and eternal happiness; he was raised up of God as man and Mediator, and sent to bless his people, ( Acts 3:26 ) .
