It means sacrificial love. It means putting someone else's life before your own. You see it in a pregnant mother. You see it in an adult child caring for their elderly parent. You see it when a student that sees a classmate being left out and includes them. These are all people who are using their existence to Give Life. Give Life is about action. Instead of using words, action is required. We can choose to Give Life in a big way like adopting a child or we can choose to Give Life in a multitude of small ways like considering how you treat and talk to others. Choose to only use words that Give Life to others.
In this world of relative truth and the emphasis on the individual, the path that leads us to pure joy is the path of taking life-giving steps of sacrificial love.
