If altruism can be learned, let's study how to love (more selflessly)!
"Assuredly, I say to you, inasmuch as you did it to one of the least of these My brethren, you did it to Me." (Matthew 25:40)
"When people who are perceptive have feelings of compassion, they know that they are being alerted by the Lord to offer help." (Emanuel Swedenborg, Secrets of Heaven 6737)
