'Kindness' in the Bible

This is our [reason for] proud confidence: our conscience testifies that we have conducted ourselves in the world [in general], and especially toward you, with pure motives and godly sincerity, not in human wisdom, but in the grace of God [that is, His gracious lovingkindness that leads people to Christ and spiritual maturity].

Working together with Him, we strongly urge you not to receive God’s grace in vain [by turning away from sound doctrine and His merciful kindness].

in purity and sincerity, in knowledge and spiritual insight, in patience, in kindness, in the Holy Spirit, in genuine love,

For you are recognizing [more clearly] the grace of our Lord Jesus Christ [His astonishing kindness, His generosity, His gracious favor], that though He was rich, yet for your sake He became poor, so that by His poverty you might become rich (abundantly blessed).

As it is written and forever remains written,“He [the benevolent and generous person] scattered abroad, he gave to the poor,His righteousness endures forever!”

Now He who provides seed for the sower and bread for food will provide and multiply your seed for sowing [that is, your resources] and increase the harvest of your righteousness [which shows itself in active goodness, kindness, and love].
