In Matthew 22:34-40, Jesus Christ is questioned by a lawyer among the Pharisees about the greatest commandment in the law. Though asked for one, He provides two, revealing a profound unity between them. He declares the first as loving God with all one's heart, soul, and mind, and the second as loving one's neighbor as oneself. These two commandments are inseparable, forming one law in two parts, essential for fulfilling God's purpose of bringing disparate parties into unity. Jesus emphasizes that on these two commandments hang all the Law and the Prophets, indicating they are the foundational principles from which all other laws and teachings depend. The second Great Commandment, to love one's neighbor as oneself, is directed toward human relationships and is constrained by human nature, limited to equality with self-love. It stands in contrast to the absolute, wholehearted love required for God in the first commandment. Both are necessary for the process of achieving oneness with God; neglecting either undermines the harmony and union He seeks. Loving one's neighbor selflessly and impartially, as God does, is a path toward perfection and a demonstration of love for Him. In I John 3 and 4, the necessity of this dual love is reinforced, showing that love for God cannot be separated from love for one's brother or neighbor. Failing to show love to others indicates a lack of love for God, placing one outside the bounds of the elect until repentance occurs. Jesus further illustrates this in John 15:12 and John 13:35, stating that loving one another as He loves us is a sign of discipleship and evidence of love for God. Even in Matthew 5, He raises the standard, urging love for enemies as well as neighbors, reflecting the perfection of the Father who loves all. The breaking of the second Great Commandment is exemplified early in Genesis 4 with Cain and Abel. Cain's jealousy and disobedience lead to the murder of his brother, a profound act of disunion that violates love for neighbor. This act, coupled with ignoring God's warning, also breaks the first Great Commandment, resulting in Cain's exile, mirroring the separation from God experienced by Adam and Eve. These early sins demonstrate the consequences of failing to uphold both commandments, disrupting the unity and communion God desires. Thus, the two Great Commandments regulate harmonious living through love of God and love of neighbor. Breaking either severs unity with both God and man, halting progress toward oneness, perfection, and eternal life until repentance restores the relationship.

The love of God is the true essence of what the world desperately needs, a love that brings peace, harmony, joy, happiness, fulfillment, purpose, and brotherly affection to all mankind. This love, defined as agape, reflects God's willful direction toward humanity, always seeking what is best for us, even when it differs from our desires. As John 3:16 reveals, God so loved the world that He gave His Son as a sacrifice, not to fulfill human wants, but to meet our deepest need for justification and reconciliation with Him upon repentance. God's love is characterized by benevolence, a disposition to do good, marked by kindness, sympathy, and generosity in individual dealings, while His overarching plan is philanthropic on the grandest scale, aiming to elevate mankind into the Kingdom of God. This love originates from God Himself, reflecting His Spirit in us, and as we exhibit it, we take on the nature of our Father. Those who reflect this love show they are born of Him, while those who do not, regardless of their knowledge, fail to truly know God. The proof of God's love is evident in the world He has provided, where rain falls on the just and unjust alike, in His patience toward us, and most profoundly, in sending His Son as a sacrifice to reconcile us to Him. Even when we were ignorant of His ways and opposed to Him, He loved us and desired the best for us. As I John 3:16 states, we perceive God's love because He laid down His life for us, and in like manner, we are called to lay down our lives for the brethren, perfecting His love in us through active application toward others. Jesus taught in John 13:35 that love for one another identifies His disciples, serving as a sign of belonging to God, just as keeping the Sabbath does. Perfect love casts out fear, and as we grow in it, we take on His nature, gaining boldness to stand before Him. We love Him because He first loved us, and this love is not ours but God's love working through us, urging us to love our fellow man as the Father and Son love us. The greatest commandment, as Jesus declared, is to love the Lord with all our heart, soul, mind, and strength, submitting every faculty to His will and devoting ourselves to glorify Him by being like Him in all we do. The first four commandments show direct love to God, requiring us to honor Him above all else, rid ourselves of idols, represent His name with honor in every aspect of life, and keep the Sabbath as holy time to rest, study, and encourage one another. The second great commandment, to love our neighbor as ourselves, extends this love to all around us—family, friends, countrymen, and even enemies—by seeking their good, refraining from harm, and showing kindness, even when their actions do not warrant it. True love of God produces a desire to live His way, embracing His commandments not as burdens but as essential boundaries that train us to become like Him. Obedience to His Word, as John states, perfects His love in us, establishing an intimate relationship with Jesus and the Father, leading toward becoming members of the God Family. If true love exists in the heart, it will be reflected in our way of living, demonstrating that we belong to Him through our outgoing concern for others. Above all, we are to put on godly love, forgiving as we have been forgiven by Christ, uniting all aspects of God's calling and opening His mind for us to emulate.
