Ministers should most definitely consider their image. Now, I don’t mean so much in how they dress and comb their hair, but in how they behave as a Christian. In fact all Christians need to be very mindful of their image. It is of upmost importance that all believers in Christ hold high moral standards for their image. For the scriptures read:
1 Peter 2:9-12
Is your image portraying that of Christ’s?
