Believers should be open to and encourage the Spirit's moving within each one, including the spontaneity from individual initiatives when gathered together. Believers need to be vigilant to prevent formality of liturgy where the Spirit is stifled, and individual initiatives are not allowed.
Every believer is called to teach and each needs to exercise toward this function. Otherwise, they will remain a babe and never mature. Sharing what the believer has learned should begin as soon as a person comes to know the Lord.
