In Matthew 22:34-40, we encounter the profound teaching of the two Great Commandments. A lawyer among the scribes, seeking to challenge Jesus Christ, asks for the greatest commandment in the law, expecting a single answer. Yet, He responds with two, revealing a deeper unity. He declares that the first is to love the Lord your God with all your heart, with all your soul, and with all your mind. The second is to love your neighbor as yourself. These two, though distinct, are inseparable, forming one cohesive law in essence. He emphasizes their foundational role by stating that on these two commandments hang all the Law and the Prophets, meaning every other precept, statute, and judgment depends on them. These commandments serve as the necessary principles for uniting two different parties within God's purpose—God and man—into one. The first directs absolute, wholehearted love toward God, while the second calls for love toward neighbors, constrained by human nature to equality with self-love. Both are essential to the process of achieving harmony and oneness with God. Neglecting either undermines this union, as loving God cannot be separated from loving others, nor can loving others stand without loving God. In I John 3 and 4, this connection is reinforced, showing that love for God and love for brethren are intertwined. Failing to show love to a brother indicates a breach in one's relationship with God, serving as a measure of one's spiritual standing. Similarly, in Matthew 5, Jesus Christ sets a high standard, urging love for everyone—brethren, neighbors, even enemies—as a path toward perfection, mirroring the Father's impartial love. By obeying this command, we demonstrate love for God, as serving others is akin to serving Him. The breaking of these commandments is evident early in humanity's history in Genesis. Adam and Eve's disobedience in the Garden of Eden reveals a failure to love God with all their being, choosing instead selfish desires, resulting in separation and disunion from Him. Likewise, Cain's murder of Abel exemplifies a profound lack of love for his brother, breaking the second commandment while also defying God, leading to exile and further disunity. These early sins illustrate the consequences of violating the two Great Commandments, severing communion with both God and man, and halting progress toward oneness. Thus, in this life, we must account for two parties—Godkind and humankind. The two Great Commandments regulate harmonious living through love: love of God and love of neighbor. Breaking either disrupts both, leaving us disunited until repentance, and obstructing the path to perfection and eternal life.
