Matt And Jesus said unto them, Because of your unbelief: for verily I say unto you, if ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible into you.
One of my favorite verses from the beginning of The Bible. What this post doesn't reflect is the power in which Moses relays this to the Israelites in the wake of their doubt towards God. It is so powerful. Trust God and He will take care of everything.
