Matthew 21:1-3 ...Jesus sent two disciples, saying to them, "Go to the village ahead of you, and at once you will find a donkey tied there, with her colt by her. Untie them and bring them to me. If anyone says anything to you, tell him that the Lord needs them, and he will send them right away."
At first glance this looks as if Jesus' lordship overrides the need to show respect by asking for the permission to use something.
But deeper study and looking into the actual verse revels to us that Jesus had a relationship with the owner of the donkey. Jesus gives great detail to what to look for and where to find it; he clearly had been there before.
I imagine there was a time when Jesus visited the man and during a conversation the man said something to the fact of, "Jesus, if ever I can do anything for you, let me know."
The time came for a need, and Jesus was able to call on this friend for that favor.
I remember long ago, my brother was just 4 or 5 years old I was just 10 or 11 and taking him to children's church. He saw the Children's Pastor and asked him for money for the soda machine. Right then and there! I stared to correct him and tell him how rude it was to ask such a thing. But before I could get the words out of my mouth the minister smiled and handed him 50 cents then patted me on the head and said, "you have not because you ask not."
I've carried that lesson with me for over 20 years.
My spiritual father told me once that humans, by nature, are not giving; giving comes the Holy Spirit probing us to do so. So when someone says "if I can do something for you let me know" they are being sensitive and open to God to work through them.
I had a friend offer his help and I had a need. Long story short I was able to simply sit in his office and ask if he was able to meet that need. He was and he did.
As I write this I am still in awe of God's goodness and this man's kindness towards me and my family. Because of him I am now the owner of a wonderful video camera that will be well used for ministry trips, filming jobs and video contest.
Be mindful of people's ability to meet a need. Ask and you shall receive.
