"How is it then, brethren? Whenever you come together, each of you has a psalm, has a teaching, has a tongue, has a revelation, has an interpretation. Let all things be done for edification." I Corinthians 14:26 (NKJV)
Assuming that you gather with your church family on Sundays, what are you planning to bring? The above verse from I Corinthians indicates that the folks in that church (despite its myriad problems) actively brought something with them to the church gathering. In many cases, this seems to have been directly related to the exercise of their spiritual gifts. Paul wanted to be sure that this was all done for the purpose of mutual edification.
It is safe to say that in the modern church the majority of people do not prepare to take something with them to build others up. Instead, most people arrive at the gathering unprepared. They may very much be looking forward to what will happen during their time with their church family, but this does not mean that they are prepared to build one another up.
On a related topic, if you did bring something with you, would you have an opportunity to share it during your church gathering? Would you be invited to do so?
Back to the topic at hand: preparation. It may be that our preparation is more a mindset than something more tangible such as a teaching. It may be a mindset of seeking out others to exhort and encourage. Regardless, we should all at least be prepared to use our spiritual gifts to serve one another.
I'm paraphrasing the following from Dave Black: Many churches have a slogan that reads something like, "Enter to worship. Depart to serve." Instead, it should read, "Enter to serve. Depart to worship."
As we gather with our church family (regardless of denomination, worship style, traditions, etc.), let's all bring something with us. Maybe this will be something a bit structured such as a teaching or a song. Maybe it is simply a mindset of being open to the leading of the Holy Spirit to share a word of prophecy. Whatever we do, let's be prepared by bringing something.
