Not all believers follow Jesus.
One who believes that Jesus is God and receives forgiveness for sins by His death, burial and resurrection is saved.
One who is saved, studies God's word, obeys it's teachings and commands is a disciple and a follower of Jesus.
One who is a follower of Jesus is filled with The Holy Spirit, taught by the Holy Spirit and empowered by The Holy Spirit to become like Jesus.
One who is like Jesus does the works of Jesus so that He may become known to those who do not know who Jesus or His Father is.
A true Christian is one who gladly picks up his cross and follows Jesus with the purpose of ending their own life by death to self with the goal of becoming alive in Christ Jesus.
