The term disciple can mean (1) learner and/or (2) follower. This was an early name for believers in Jesus Christ as the promised Jewish Messiah. It is important to note that the NT calls for disciples, not mere decisions (cf. Matthew 13; 28:18-20). Christianity is an initial decision (repentance and faith) followed by an ongoing decision of obedience and perseverance. Christianity is not a fire insurance policy or a ticket to heaven, but a daily servant/friend relationship with Jesus.
