The power of Jesus's authority in Luke 19
When he drew near to Bethphage and Bethany, at the mount that is called Olivet, he sent two of the disciples, saying, "Go into the village in front of you, where on entering you will find a colt tied, on which no one has ever yet sat. Untie it and bring it here. If anyone asks you, Why are you untying it? you shall say this: 'The Lord has need of it.'"
So those who were sent went away and found it just as he had told them. And as they were untying the colt, its owners said to them, Why are you untying the colt? And they said, "The Lord has need of it."
Maybe this is the key to living in the power and authority that he has passed on to us, being able to say boldly, "The Lord has need of it."
