Religion does not teach us to be bitter but better. It teaches us to accept life on an as is where is basis. It teaches us to open up, encompass, absorb..be a sponge for all the good and the goodness there is. It teaches us to let go..of bitterness, hard feelings, sadness and celebrate life.
If at all religion asks us to change something its never been on the outside but within..for the outer shell is just that – a shell. If we want to make a a difference in this world then we need to change just one person and that would be us. We can upgrade ourselves to be a better human being full of love, warmth and acceptance. We can wipe out our insecurities to revel in the glorious soul within. Whether we choose to do this or not is entirely our decision in end.
