Mistakes in text

Today, I would like you all to realise that only those of us who believe in X religion can fundamentally solve misfortunes and problems. I ask you to say a prayer every morning and evening, and participate in the propagation of our religion.Let's have meetings to study our religion together, and make an effort to improve our own personalities. By propagating our religion, we can bring true peace and tranquillity to the world.
Can someone point out mistakes in the above text? Thanks.
