The Message Bible says it this way, “Love cares more for others than for self.”

Webster's 1812 Dictionary gives this definition of the word “kind”:

1. Disposed to do good to others, and to make them happy by granting their requests, supplying their wants or assisting them in distress; having tenderness or goodness of nature; benevolent; benignant.

From my other Bible helps we have these comments:

The word used here denotes to be good-natured, gentle, tender, affectionate. Love is benignant. It wishes well. It is not harsh, sour, morose, ill-natured. Tyndale renders it, “is courteous.” The idea is, that under all provocations and ill-usage it is gentle and mild. “Hatred” prompts to harshness, severity, unkindness of expression, anger, and a desire of revenge. But love is the reverse of all these. A man who truly loves another will be kind to him, desirous of doing him good; will be “gentle,” not severe and harsh; will be “courteous” because he desires his happiness, and would not pain his feelings. (From Albert Barnes notes on the Bible)

It is tender and compassionate in itself, and kind and obliging to others; it is mild, gentle, and benign; and, if called to suffer, inspires the sufferer with the most amiable sweetness, and the most tender affection. It is also submissive to all the dispensations of God; and creates trouble to no one. (Adam Clarke's Commentary on the Bible)

Our Heavenly Father displayed such kindness towards us. Look at Titus 3:-7: “For we ourselves also were once foolish, disobedient, deceived, slaving for various lusts and pleasures, living in malice and envy, hateful, hating one another. But when the kindness and love of God our Savior toward man appeared, not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewal of the Holy Spirit, whom He poured out on us abundantly through Jesus Christ our Savior, that being justified by His grace, we should become heirs according to the hope of eternal life.”

Isaiah tells us that God's kindness is everlasting. “I hid my face from you for a moment in a burst of anger, but I will have compassion on you with everlasting kindness," says the LORD your defender.” Isaiah 54:8

God shows perfect love toward us. With Him living in us, we can also show a true, Christ-like love for others. We just have to invite Him in.
