There is another truly wonderful bit to pull from that icon of Adam I like so much.
Just as the Ancient of Days calls Adam to life with His breath of life and gives him a name and vocation, standing by his side as he fulfills it, so too the Ancient of Days calls us to life in Baptism. We then are all “Little Christs,” growing from His vine going about our vocations with Him beside and in us. We are remade in His image as God’s own sons (Eph 1:5; Col 3:10).
Wherever there is such faith and assurance of grace in Christ, you can also confidently conclude with regard to your vocation and works that these are pleasing to God and are true and good Christian fruits. Furthermore, such temporal and physical works as governing a land and people, managing a house, rearing and teaching children, serving, toiling, etc., also develop into fruit that endures unto life everlasting. Thus the holy patriarch Abraham and our holy ancestress Sarah will be commended and praised on Judgment Day for their marital life. Although the married estate will come to an end and be no more, as will all the life and activity of this world, yet this holy Sarah, and others with her, will receive their little crowns because they were pious spouses and mothers, not by reason of their works per se—for these had to cease—but because they did these works in faith. In like manner, the works of all Christians are performed to God’s everlasting pleasure; they will not be despised, as will those of non-Christians, but will have their eternal reward also in yonder life, because they are works done in Christ and grow from the Vine.
