The entire law or scripture is summed up in a single command. Guess what it could be? It's nothing else but love your neighbour as yourself, scripture reference (Galatians 5 : 14). So, says the scripture and I'm saying the same thing. You've got to love all and sundry, even if you don't like them. Do you hate at the expense of love? If yes then, please do away with hatred and kindly replenish yourself with love. For, a call to love all is a divine command which you should strictly adhere to. Yes of course, you should love and never hate. Besides, God first loved us. So that we can love one another in return. Therefore, love all and hate none.
The essence of being human is that one does not seek perfection that one is prepared in the end to be defeated and broken up by life, which is the inevitable price of fastening one's love upon other human individuals.
The greatest gift a parent can give a child is unconditional love. As a child wanders and strays, finding his bearings, he needs a sense of absolute love from a parent. There's nothing wrong with tough love, as long as the love is unconditional.
