Final answer:
Baptism, Communion, and Confession are necessary for converts to grow in testimony and faith.
Step-by-step explanation:
Three things necessary to help converts grow in testimony and faith are:
Baptism: Baptism is believed to be necessary for the removal of original sin and the initiation into the Christian faith. It symbolizes a spiritual rebirth and commitment to Jesus Christ.
Communion: Communion, also known as the Eucharist or Lord's Supper, is a ritual where Christians partake in the bread and wine, which symbolize the body and blood of Christ. It is a way for believers to spiritually connect with God and strengthen their faith.
Confession: Confession is the act of acknowledging and repenting for one's sins. Through confession, converts can seek forgiveness from God and grow in their relationship with Him.
