It may not be true to life, either, because as human beings every event we go through changes us in some way. You might have a great plot for your story, but if it doesn’t affect your main character in some way it will lack depth. Perhaps your protagonist might have learnt something about themselves along the way, come to a particular decision, found a new and needed skill, or in some way improved themselves or decided to improve the lives of others.
If, during the process of your story, your character becomes a Christian, you will have needed to move them on from perhaps being diffident or antagonistic to realising their need for a saviour, to recognising that Jesus is the way. You don’t, of course, have to do that, just because you are writing ‘Christian fiction’ – that’s just by way of example. Equally, your protagonist may have gone through a process from being fearful of a particular situation to finding peace. They may have gone from being excluded from school due to their destructive anger to channelling their anger into working for a positive change in attitudes at their community . . . the possibilities are, of course, endless.
If you have a manuscript already written, have a read through and see how your main character if different at the beginning of your story than at the end. Is the change obvious, realistic, inspirational? Will it encourage your readers?
