“Go therefore and make disciples of people of all the nations, baptizing them in the name of the Father and of the Son and of the holy spirit,

Matthew 28:19, 20.

¹¹ Note that newly taught Christians were to be baptized in the name of the holy spirit. This holy spirit is not a person but the active force of Jehovah God, which He employs by means of Jesus Christ. At Pentecost, Jehovah God, through Jesus, poured out this active force upon the dedicated followers of Jesus Christ. (Acts 2:33) They were filled with this holy spirit, and one of the expressions, or fruits, of the holy spirit is joy. (Galatians 5:22, 23; Ephesians 5:18-20) Joy is a stimulating quality. The disciples are to be filled with the joy of the holy spirit. The prayer worded by the apostle Paul is most appropriate: “May the God who gives hope fill you with all joy and peace by your believing, that you may abound in hope with power of holy spirit.”​—Romans 15:13.

¹² Filled with this joy-inspiring spirit, Witnesses of Jehovah today, including the “great crowd,” will want, yes, will be moved, to encourage one another in the midst of this unfriendly system of things. Accordingly, the apostle Paul spoke of “an interchange of encouragement.”​—Revelation 7:9, 10; Romans 1:12; 14:17.
