Mark 14:12-16
And the disciples set out and went to the city and found it just as he had told them, and they prepared the Passover. (Mark 14:16 ESV)
Jesus told his disciples that if they went to a certain house and asked for it to be made available to them the owners would accommodate them. It worked out exactly like he had said. Interestingly, the Scriptures record that the disciples then prepared the Passover meal.
I don't know how familiar you are with Passover but it is a long meal. It can last upwards of four hours and is quite the experience. Passover was a big deal for the Jews. Jesus took the opportunity at his final such meal with his disciples to reinforce some ideas. It was their final hours together as a group before his arrest. And the disciples prepared the Passover.
You see sometimes before God can do the work He wants to do, we have to prepare for it. Not that He needs us, or couldn't work without us, but He chooses to accomplish things through us. Sometimes that season of preparation, no matter how long or short, is exactly what we need to experience us to position us for the great work God is about to do.
