Why is it important for Christians to demonstrate kindness?

In Colossians 3:12, Paul instructs believers to 'put on kindness' as part of their Christian character. This command highlights the necessity of showing kindness, which is an expression of God's love and grace towards us. As Christians, our actions should mirror the kindness that God has shown us, particularly in forgiving and loving others, even those who may not treat us well. Demonstrating kindness serves as a witness to the transformative power of the Gospel in our lives and fulfills the law of Christ to love one another.
