I believe the answer is an attitude of intentional edification. We should arrive at the gathering with the goal of building up one another in Christ through both what we do and what we say.
The specifics of what we do probably matter less than the goal itself (edification).
For example, I Corinthians 14:26 says, "What then, brothers? When you come together, each one has a hymn, a lesson, a revelation, a tongue, or an interpretation. Let all things be done for building up." We see mentioned here some of the things that are acceptable to bring to the gathering. Surely there are others (for example prayer). It is important to notice that whatever we bring, it is to be with the purpose of helping others mature in their relationships with Jesus Christ.
In Hebrews 10:24-25, we read, "And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near." In the context of the church gathering, we should encourage one another to lives of love and good works. This is an example of what we can do to edify our brothers and sisters.
Ephesians 4:29 is a good reminder for us. Paul writes, "Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear." In every area of our lives, we are to only speak words that build up, or edify. This certainly applies to church gatherings, whether more formal or less formal.
So as you gather today, tomorrow, or some other time, purpose to take specific things with you such as a teaching, a psalm, a hymn, a prayer, a word of exhortation, a word of encouragement, a word of confession, a tongue (yes, I wrote that), a revelation, a word of prophecy, etc.
Whatever you bring, plan to participate by doing things that build up your brothers and sisters in Christ.
God receives worship He enjoys when we focus on the good of others. Let that be our goal as we come together.
