True Kindness is within the Heart and Never Changes

A kind person is kind to everyone all the time, those who are rude to some and friendly to others are rude or they couldn't even be rude to one person.

Those who show favoritism have arrogance in their hearts, full of self-exaltation as they look down their noses at those they wish were beneath them.

 
1 John 4:7-8
"Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God"

 
1 Corinthians 13
"If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal"

 
Ephesians 4:1-6
"Be completely humble and gentle; be patient, bearing with one another in love"

 
1 Peter 4:8
"Above all, love each other deeply, because love covers over a multitude of sins"

 
Colossians 3:14
"And over all these virtues put on love, which binds them all together in perfect unity"

 
Matthew 22:36
"Love the Lord your God with all your heart and with all your soul and with all your mind. This is the first and greatest commandment. And the second is like it: 'Love your neighbor as yourself'"

 
When we love as Christ loved we will be the same with everyone all the time, it is not in our nature to treat others disrespectfully.
