As the Church grew, so did the number of people who opposed it. But the Lord still wanted missionaries to share the gospel. In a revelation to Joseph Smith and Sidney Rigdon, the Lord promised that “no weapon formed against [them] shall prosper.” (D&C 71:9) The Lord would protect His Church and it would continue to grow. Because of the growth of the Church, bishops needed to be called. The first bishop called was Edward Partridge. In section 72, Newell K. Whitney is called to be a bishop. Bishops are called to help the Saints under their stewardship and to care for the poor and needy. 

The missionaries, bishops, and the Saints were asked to be faithful. In section 75, the Lord reminds the Church to pray always so the Comforter (the Holy Ghost) can be with them. If they are faithful, they “shall overcome all things.” (D&C 75:16)
