We know the things Jesus said about doubting. “You of little faith,” he said, “why did you doubt?” (Matthew 14:31NIV) And in Mark 11:23(NIV) Jesus said: “Truly I tell you, if anyone says to this mountain, ‘Go, throw yourself into the sea,’ and does not doubt in their heart but believes that what they say will happen, it will be done for them.” This suggests that doubt gets in the way of our breakthrough.
