This Sunday is the congregations' Mission Festival, so there is not only a guest preacher, but I managed to pick someone who was interested in preaching on the Gospel text for Trinity Sunday--which is also this Sunday.
For this year, the Gospel text for Trinity Sunday is Matthew 28:16-20, and this text is possibly one of the most well-known (and possibly also the most misunderstood) verses within the New Testament.
I have lost count of how many times I have heard of a person who travelled a significant distance in the hopes of doing some evangelism, and unfortunately, in the end, things did not turn out too well for that person. This is understandable because we live in a very sinfully complex world. That is a sad fact that is sometimes forgotten.
It is good to remember as well that the word 'Go', when Jesus says to his disciples, 'Go therefore and make disciples of all nations...,' the word essentially means, 'As you are going....' The important thing is definitely not the going; the far-more important thing is the disciple making.
Jesus makes that aspect easy to comprehend (since the word is somewhat rare) by stating the two components of disciple making: baptizing and teaching. By the way in which both of those things are laid out, it should become obvious, sooner or later, that the focus should not be ourselves in any way. The focus should be Jesus as the one who changed our situation completely around. The meaning of his name (Savior) proves it.
As he changed Matthew the tax-collector, as he changed the girl who was dead, so he will continue to change people by the words he gives through the mouths of those who are willing to speak them. A seminary professor of mine used to say, 'To be ordained is to be rendered irrelevant.'
