Jesus said there are two great commandments, one of which is to 'love your neighbour as yourself' (Matt 22:34-40). But if we say we can't love others until we love ourselves, we are essentially saying Jesus gave us a third commandment.
In fact, without realizing it, we are suggesting that to love yourself is the second greatest commandment, for we are saying it comes before the commandment to serve others. We are saying that loving ourselves is a precondition to loving other people.
Phil 2:2-4 Make my joy complete by being like-minded, having the same love, being one in spirit and of one mind. Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, not looking to your own interests but each of you to the interests of the others.
JOY: Jesus first, Yourself last and Others in-between...
