A GENUINE BELIEVER IN JESUS CHRIST LIVES IN TWO WORLDS

Jude 3

3 Beloved, my whole concern was to write to you in regard to our common salvation. [But] I found it necessary and was impelled to write you and urgently appeal to and exhort [you] to contend for the faith which was once for all handed down to the saints [the faith which is that sum of Christian belief which was delivered verbally to the holy people of God].
