The New Testament makes it clear that when people come to faith in Christ they now become spiritual newborns. In other words, they are spiritual infants that must continue to grow.
New believers are susceptible to being carried away by false doctrine so the church must be on guard against any error entering the church.
Christ declares that the means by which His church grows is the truth of the Word of God.
God has gifted certain men in the local church to teach and train their congregations from the truth of God’s Word.
The apostle Paul clearly states that the Lord Jesus Christ is the head of His church.
Christians must be committed to the local church. Christ designed the church to function the best when its members are fully committed.
