Come ye, and let us go up to the mountain of the Lord, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the Lord from Jerusalem. Isaiah 2:3.
The Old Testament Scriptures were the lesson book of Israel. When the lawyer came to Christ with the question “Master, what shall I do to inherit eternal life?” ... the Saviour said, “What is written in the law? how readest thou? And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbor as thyself.” Christ said, “Thou hast answered right: this do, and thou shalt live” (Luke 10:25-28)...
If there were not another text in the Bible, this statement carries sufficient light and knowledge and assurance for every soul. The lawyer had answered his own question, but willing to justify himself, he said to Jesus, “Who is my neighbor?” (Verse 29). Then by the parable of the Good Samaritan, Christ showed who is our neighbor, and gives us an example of the love we should manifest toward those suffering and in need. The priest and Levite, whose duty it was to minister to the needs of the stranger, passed by on the other side.
At the conclusion of the narrative Christ asked the lawyer, “Which now of these three, thinkest thou, was neighbor unto him that fell among the thieves? And he said, He that shewed mercy on him. Then said Jesus unto him, Go, and do thou likewise” (Verses 36, 37).
There are practical lessons in the Word of God... That Word teaches living, holy principles, which prompt men to do unto others as they would have others do unto them, principles which they are to bring into the daily life here, and carry with them into the school above... The altar and the plough are the experiences for all who seek eternal life. We know altogether too little of the greatness of the love and compassion of God. Let students put to the stretch the faculties of their mind, that they may comprehend such chapters as the forty-fifth of Isaiah, which should be placed in form, and brought into our schools as valuable studies. They will be better than romance or fable. Why have our schools been so dependent upon books which tell so little of the city we claim to be seeking, whose Builder and Maker is God? ... Heaven is our home. Our citizenship is above, and our lives must not be devoted to a world which is soon to be destroyed. We need the Word of God revealed in living characters. What pure, excellent language is found in the Word of God! What elevating, ennobling principles!—Manuscript 96, July 20, 1899. “The Bible as Our Study Book.”
