Many times you will not 'feel' like worship. Perhaps you have had so many disappointing experiences in the past that you think it is hardly worth it. There is such a low sense of the power of God. Few people are adequately prepared.
But you need to go anyway. You need to offer a sacrifice of worship. You need to be with the people of God and say, 'These are my people. As stiffnecked and hard-hearted and sinful as we may be, together we come to God.' Many times I do not feel like worshiping and I have to kneel down and say, 'Lord, I don't feel like worshiping, but I desire to give you this time. It belongs to you. I will waste this time for you.'
Isaac Pennington says that when people are gathered for genuine worship, 'They are like a heap of fresh and burning coals warming one another as a great strength and freshness and vigor of life flows into all.'' One log by itself cannot burn for very long, but when many logs are put together, even if they are poor logs, they can make quite a fire.
