The purpose of follow-up is doctrinal, personal and collective.
Note that follow-up still has a threefold purpose first, doctrinal;
the new believer must be taught Bible doctrine. No believer can
advance spiritually on his own. Were it true that all a Christian
need do in order to grow in grace and in to the knowledge of his
Savior is read a chapter or two of Bible daily, the Lord would not
have found it necessary to give certain men the gift of pastor-teacher
(Eph. 4:11)! It is the duty of the pastor-teacher to feed the flock of God,
to edify and equip the saints (Eph. 4:12). God designed the local church
to be the believer's classroom.
