Although informal assemblies have some apparent advantages, you will find little support for them in the Word of God. This, to say the least, should lead us to question the advisability of assigning superior value to them. Casualness and godliness are not easily joined. It requires an extraordinary amount of spiritual discipline to bring them together. The reason for this condition is clear.
Informality tends to give the upper hand to our lower nature.
It operates more freely in that type of surrounding. This was one of the besetting sins of the Corinthian assemblies. We encourage the opening of our assemblies with prayer, and the singing of disciplined praise to God. It is also refreshing and beneficial to our spirits to enjoy the reading of Scripture. Entered into properly, these help us to break out of debilitating casualness, making us more alert to God and, consequently, more available for His blessing.
