Hymn #52 (Hymns) is a very good hymn on the worship of the Father. Stanzas 2 and 3 say:
This hymn is simple and short, yet high in its thought and full of light. It would be good to ask the saints to read these stanzas so that they can be impressed with the significance of worshipping the Father.
Related to our partaking of the Lord's table, there is also a warning in the Scriptures.
We have to prove ourselves and discern the Body at the Lord's table (1 Cor. 11:28-29). We have to discern whether the bread on the table signifies the unique Body of Christ or a sect, a division, a denomination. This is why we can take the Lord's table only in the local churches. We cannot partake of the so-called communion in other places because that bread on the table does not signify the Body but a division. Whenever we go to a place to attend the Lord's table, we must prove to ourselves that the bread on the table really signifies the Lord's Body, without any division.
