You shall keep my sabbaths, and reverence my sanctuary: I am the LORD.
Worshipping alone is like a solo in music, very beautiful and entrancing, with charms that no chorus can give. Worshipping together is like an anthem with its harmonies sung by a large chorus. There are powers in it and emotions awakened, which no solo, however beautifully sung, can produce. Christians who worship in the house of God in company with other Christians will receive blessings that they would not receive worshipping by themselves.
