How do we know that showing kindness is important for Christians?

In Romans 12:10, Paul encourages believers to be kindly affectioned one to another with brotherly love. The emphasis here is on genuine affection and the need to prioritize the well-being of others. This principle is rooted in the character of Christ, who exemplified perfect kindness and love throughout His ministry. As Christians, we are called to imitate Christ, who said in John 13:34 to love one another as He has loved us. This establishes kindness as not just an option but a fundamental aspect of the Christian life that demonstrates our faith and reflects God’s love to the world.
