Christ has said: “Where two or three are gathered together in My name, there am I in the midst of them.” Matthew 18:20. Wherever there are as many as two or three believers, let them meet together on the Sabbath to claim the Lord’s promise.

The little companies assembled to worship God on His holy day have a right to claim the rich blessing of Jehovah. They should believe that the Lord Jesus is an honored guest in their assemblies. Every true worshiper who keeps holy the Sabbath should claim the promise: “That ye may know that I am the Lord that doth sanctify you.” Exodus 31:13.

The Sabbath was made for man, to be a blessing to him by calling his mind from secular labor to contemplate the goodness and glory of God. It is necessary that the people of God assemble to talk of Him, to interchange thoughts and ideas in regard to the truths contained in His word, and to devote a portion of time to appropriate prayer. But these seasons, even upon the Sabbath, should not be made tedious by their length and lack of interest.478
