The disciples see Jesus doing something and they do not question it. They do not go up to him and say, Jesus we don’t like the way you are doing this. They don’t try to convince Him that this woman is a lost cause. They wait till he finishes talking to her and then they try to get Him to eat.
Jesus response to them is that He has food they know nothing about. This throws them off because they know He didn’t have any food. They are discussing this among themselves when Jesus says “My food, is to do the will of him who sent me and to finish his work.
Jesus was just letting them know that sometimes meeting the needs of others and serving God is more important that worrying about what we want at the moment. It is easy for us thinking of the things we need to get done and forget that God may have placed someone there who needs us. It might be someone that normally because of social or class norms we wouldn’t reach out to. But that is our food! The will of God should always be what we feed on.
Jesus finishes up by comparing telling people about Him to raising crops. He is saying the seeds planted these people are just waiting to be harvested. When we look around us we sould see others as Those whom God has planted a seed in all they need is that last bit of work to get them out of the fields.
Jesus tells us others have done the hard work and we need to enjoy the benefits of that work in this case the prophets and John served to be the way God planted the seed. Jesus just showed up and spoke to a woman in compassion and it led to many in the town being saved.
As you go through your week are you looking over the fields and harvesting the fruit God has planted?
