What won't you do simply because no one asked you to? How childish many Christians are when work needs to be done yet they won't lift a finger to help, "...because no one asked me?" Pathetic! They could clearly see the task and knew someone would probably end up doing it, but "not me, not unless someone seeks me out and shows me that I'm important enough to be needed!" Again, pathetic and self-centered.
This woman mentioned in Luke 7:36-50 saw a need and out of her gratitude for Jesus, jumped in and showed Him her love and willingly took the place of a housemaid and washed Jesus' feet and gave Him honor that others wouldn't perform. She didn't have to be asked. She saw a way to show Jesus her love and she simply did what she could. Oh yes! She was criticized by the Pharisee, but she was commended by the Lord!
What needs to be done in your church? What neighbor faces a daunting task and could use some help, but doesn't want to bother other people, but sure would appreciate someone who was willing to help them? Who has been seeking to meet those needs? Did they have to wait to be asked, or were they the kind of Christian who saw the need and simply decided they were available and they were able, so they just did what was needed. They did what they could because "that's what a Christian does."
I have an old saying that fits here: "Whoever first sees a task that needs to be done, and they are capable to do it, well, they should simply go ahead and do it!" And they should do so without waiting for an invitation! They do what they can because they do it for the Lord.
