In saying by this Jesus is saying this quality exclusively is the defining mark that distinguishes those around Jesus from those who really do know him. by this means that Jesus is saying: I do not distinguish my followers by their money, influence, social prominence, social media followers or annual budgets. by this means there is a new law, a new covenant at work and if you cannot follow it then you do not know me. It doesn’t matter what other great things you can do. Jesus laid down his life for us. Do not be deceived: there is no other way to be like Jesus than to give your life for others.
