How should Christians love their neighbor?

Christians are called to love their neighbor with a profound, selfless affection known as agape love, which transcends mere sentimentality or preference. This divine command stems directly from the two greatest commandments articulated by Jesus: to love God with all one's heart, soul, and mind, and to love one's neighbor as oneself, as recorded in Matthew 22:37-39. This love is not conditional upon the neighbor's character or actions; rather, it is an active, volitional commitment to seek their highest good, even at personal cost. Jesus explicitly taught this expansive definition of 'neighbor' in the Parable of the Good Samaritan (Luke 10:29-37), demonstrating that one's neighbor includes anyone in need, even those traditionally considered enemies or outsiders. The practical outworking of Christian love for neighbor involves several key aspects. It necessitates compassion, which means actively identifying with another's suffering and seeking to alleviate it. It demands forgiveness, as seen in Jesus' teaching to forgive seventy times seven (Matthew 18:21-22). It includes practical acts of service, such as feeding the hungry, clothing the naked, visiting the sick, and welcoming the stranger, as described in Matthew 25:35-40. Furthermore, this love extends to non-retaliation against those who cause harm, praying for one's enemies, and striving for reconciliation (Matthew 5:44). Ultimately, loving one's neighbor also encompasses sharing the Gospel, for the greatest good one can offer another is the knowledge of salvation through Jesus Christ. This love fulfills the Law, as highlighted in Romans 13:8-10, where Paul states that "Love doesn't harm a neighbor. Therefore love is the fulfillment of the law." It is a distinguishing mark of true discipleship, empowered by the Holy Spirit within believers.

The concept of 'neighbor' in ancient Israelite society, as derived from the Torah (e.g., Leviticus 19:18), primarily referred to fellow Israelites or resident aliens who lived under the Mosaic Law. During the Second Temple period, particularly in Jesus' time, sectarian divisions further narrowed this definition for some groups, often excluding Samaritans, Gentiles, and even certain fellow Jews deemed 'sinners.' The animosity between Jews and Samaritans was deeply entrenched, stemming from historical, ethnic, and religious differences, including differing views on the proper place of worship (Jerusalem vs. Mount Gerizim). Jesus' teaching, particularly the Parable of the Good Samaritan, radically challenged these ethnocentric and legalistic interpretations, pushing beyond the conventional boundaries. By featuring a Samaritan as the hero and the priest and Levite (religious leaders) as those who failed to act, Jesus critiqued the prevailing societal norms and religious hypocrisy, expanding the definition of neighbor to universal proportions, embracing anyone in need, regardless of their background or social standing. This was a revolutionary concept that dismantled tribal and religious barriers.

The theological insight derived from the command to love one's neighbor is profound: it is an immutable reflection of God's own character and a primary means by which humanity fulfills its intended purpose. Agape love, being a divine attribute, is poured into the hearts of believers by the Holy Spirit (Romans 5:5), enabling them to love in a way that is humanly impossible. This love is not merely an ethical injunction but a spiritual reality, demonstrating the new life in Christ. Loving one's neighbor is inseparable from loving God; one cannot claim to love God whom he has not seen if he does not love his brother whom he has seen (1 John 4:20). It serves as the ultimate litmus test of genuine faith, proving the transformative power of the Gospel and establishing the community of believers as a light to the world.
