Peter answers this question for us in I Peter 4:7-11. He writes:
"The end of all things is at hand; therefore be self-controlled and sober-minded for the sake of your prayers. Above all, keep loving one another earnestly, since love covers a multitude of sins. Show hospitality to one another without grumbling. As each has received a gift, use it to serve one another, as good stewards of God's varied grace: whoever speaks, as one who speaks oracles of God; whoever serves, as one who serves by the strength that God supplies — in order that in everything God may be glorified through Jesus Christ. To him belong glory and dominion forever and ever. Amen."
Of course, this passage describes how we should live all the time, not just on Sundays.
As we gather (whenever we gather), let's all use our gifts to serve one another in love that Christ will be glorified.
