It can be so easy to succumb to pride, even as a Christian. When we are serving the Kingdom in the way in which God has gifted us spiritually, we see miraculous and near-miraculous events happen. It is easy to get a little puffed up and begin to think that it was due to us that we were able to have such great results.
Look at this passage from Jesus:
7 ‘Who among you would say to your slave who has just come in from ploughing or tending sheep in the field, “Come here at once and take your place at the table”? 8 Would you not rather say to him, “Prepare supper for me, put on your apron and serve me while I eat and drink; later you may eat and drink”? 9 Do you thank the slave for doing what was commanded? 10 So you also, when you have done all that you were ordered to do, say, “We are worthless slaves; we have done only what we ought to have done!”’
Even when wonderful things happen, and tremendous results take place, it is because we are doing what we were created, gifted, and commanded to do. There really is no room for Christian pride in the results of ministry according to our giftedness by God.
