It is good to be actively doing something for the Lord, isn’t it? Whether we are teaching a Sunday School class, being a good listener, or washing dishes and changing diapers, shouldn’t we all be using our gifts/talents to benefit others and to help share God’s love? Most definitely! But, as you are busy for the Lord, are you serving Him with gladness? Or, have you become distracted from your purpose and are serving with a grudge?
We can see in Luke 10:38-40 that Martha was serving with a grudge. It might not have started out that way. I'm guessing she was happy to be using her gifts of hospitality, and excited to make her guests feel welcome but, as she took her focus off of what was most important, her attitude changed:
As Jesus and his disciples were on their way, he came to a village where a woman named Martha opened her home to him. She had a sister called Mary, who sat at the Lord’s feet listening to what he said. But Martha was distracted by all the preparations that had to be made. She came to him and asked, “Lord, don’t you care that my sister has left me to do the work by myself? Tell her to help me!”(NIV)
If you keep reading, you will see how Jesus answered Martha in a loving way, explaining to her how Mary had chosen what was better - spending time with Him over "busyness" - and it wasn’t going to be taken away from her.
Luke 10:41-42 “Martha, Martha,” the Lord answered, “you are worried and upset about many things, but few things are needed—or indeed only one. Mary has chosen what is better, and it will not be taken away from her.”
Doing things for the Lord is a good thing; Jesus does want us to be busy for Him. But, He would rather we focus our attention on HIM first of all. If we aren’t spending time with Him and keeping our focus on Him, then the things we do will only be an act of “busyness” rather than what they should be: an act of service.
Serve the Lord with gladness.
