Brethren We have to Love One Another

John 13:34
33 Little children, I am with you only a little while longer. You will look for Me, and as I said to the Jews, so now I say to you: ‘Where I am going, you cannot come.’ 34 A new commandment I give you:Love one another. As I have loved you, so also you must love one another. 35 By this all men will know that you are My disciples, if you love one another.”…

important commandments are love of God and love of neighbor (Matt. 22:34–40). Even this teaching, however, reflects the Ten Commandments. Broadly speaking, we can divide these laws into two categories. The first category, consisting of the first four commandments (having no other gods, making no images of the divine nature, honoring God’s name, and Sabbath-keeping; see Ex. 20:3–11), deals primarily with the love of God. Love of neighbor is emphasized in the second category, which includes the other six commandments (honoring parents and the prohibition of murder, adultery, theft, false witness, and covetousness; see vv. 12–17).
This twofold division, in turn, has influenced the way theologians have spoken of God’s law. Question and answer 93 of the Heidelberg Catechism divides the Ten Commandments into “two tables,” each of which corresponds to the division we noted in the preceding paragraph. Again, this is very common in church history. For example, John Calvin divides the Ten Commandments in this way (Institutes 2.8.11–12). Historically, Christian thinkers have said the stone tablets given to Moses (Ex. 31:18) reflected this division, with the first four commandments appearing on the first tablet and the second six commandments appearing on the second tablet. Archaeological discoveries, however, indicate it is possible that each tablet had all ten of the commandments inscribed upon it. In any case, the division of the Ten Commandments is sound theologically. If we want to know the specific ways to love God and neighbor rightly, we must look to the Ten Commandments.
