If someone says, “I love God,” but hates a fellow believer, that person is a liar; for if we don’t love people we can see, how can we love God, whom we cannot see?
Then Jesus told them, “I tell you the truth, if you have faith and don’t doubt, you can do things like this and much more. You can even say to this mountain, ‘May you be lifted up and thrown into the sea,’ and it will happen.”
And it is impossible to please God without faith. Anyone who wants to come to him must believe that God exists and that he rewards those who sincerely seek him.
