1 Corinthians 13 And now abideth faith, hope, charity, these three; but the greatest of these is charity.(Talks about love kindness and good deeds. Being kind begins with the thought of forgiveness.)
If we are blessed think of how we can bless others. Think about all the things you have, everything belongs to God. If you look back, think of all the kindness God has done to you.
[crossing the street story]
David was looking for Saul's people where he can show kindness.
Matthew 10:42 And whosoever shall give to drink unto one of these little ones a cup of cold water only in the name of a disciple, verily I say unto you, he shall in no wise lose his reward.
(There's reward from showing kindness to other people. 1 John 3:18 there must be actions that follows.)
When you know you should do something kind and you don't do it, it's a sin.
Comforting to those who are sick, encouraging someone who is depress, giving a helping hand to someone who is a stranger.
People returning money but being scold as a fool is a thing of the world don't be deceived.
1 Peter 8 Whom having not seen, ye love; in whom, though now ye see him not, yet believing, ye rejoice with joy unspeakable and full of glory:
(Be compasionate & humble.)
When you think they don't deserve your kindness then you don't deserve God's kindness either. Kindness is something that can't be force its not something you ask in return. We do our glorified act without expecting anything because God has already given the kindness to you.
Don't let anyone knows you're giving.
Don't give any praise report.
If we think of heaven and God's loving kindness for eternity for all opportunity we must show kindness, show hospitality to everybody.
