I have been studying Paul over the summer by reading the Book of Acts and all of Pauls' letters. The other day I was reading in 2 Tim.4:11, "...Get Mark and bring him with you, because he is helpful to me in my ministry." (NIV) Now, I seem to remember in Acts 15:37-38 that Barnabas wanted to take Mark with them on one of their journey's, but Paul "wasn't about to take along a quiter," Acts 15:38 Msg.
At some point in Paul's ministry he had an attitude adjustment toward Mark. The Message says that Paul was going to use Mark as his right hand man. Now, that is a complete turn around from what we saw earlier.
There will be times through out our ministries when people will come into our lives to help us, but we are not very impressed with them. They may not be as diligent in doing things as we are. They may not seem as committed. You may even wonder if they are cut out for ministry. Don't give up on them. Don't give up on your attitude toward them either.
God just may have some awesome duties for them to do...they just aren't ready at the moment. If they leave you for a while and come back, be willing to look into their heart and see if they have allowed God to change them, as Mark did. The one, or one's, you thought were not cut out for ministry, may very well be the very best ministry companions you ever dreamed of having.
Just thought I would throw that out there today. Who is working with you? What is your attitude toward them? Is there someone that has come back into your life that you are unsure of? Look closely and see if God has them in your life for a particular reason.
