There is no caste with God. He ignores everything of the kind. All souls are of value with Him. Laboring for the salvation of the soul is employment worthy of the highest honor. It matters not what may be the form of our labor, or among what class, whether high or low. In God's sight these distinctions will not affect its true worth. The sincere, earnest, contrite soul, however ignorant, is precious in the sight of the Lord. He places His own signet upon men, judging, not by their rank, not by their wealth, not by their intellectual greatness, but by their oneness with Christ. The unlearned, the outcast, the slave, if he has made the most of his opportunities and privileges, if he has cherished the light given him of God, has done all that is required. The world may call him ignorant, but God calls him wise and good, and thus his name stands registered in the books of heaven. God will fit him up to do Him honor, not only in heaven, but on the earth. GW 332.1
The divine rebuke is upon him who refuses the companionship of those whose names are written in the Lamb's book of life, simply because they are not rich, learned, or honored in this world. Christ, the Lord of glory, is satisfied with those who are meek and lowly in heart, however humble may be their calling, whatever their rank or degree of intelligence. GW 332.2
