“Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime. (Maimonides, although its origin is not totally known)
The Christian is not the end, but the sign post pointing to the destination of all Love.
Yet a Christian could in a way say, “Act in kindness without sharing Christ and save a man for that day, yet act in kindness to show them Christ and save that man forever in another day.”
To show kindness and love for kindness and love sake is good and should be done, yet it falls truly short of our ultimate mission on earth- If you only show kindness to merely benefit a man or woman only in his or her temporary life here then you fail to truly act in kindness if they perish forever. Do not preach the Gospel alone but also live it, but do not live the love of Christ alone and never proclaim the message of Christ. That is foolishness too!
