It is possible to call yourself a Christian and not be a follower of Christ.
A follower of Christ should always be digesting what it means to be forgiven.
Being forgiven by grace through faith in Jesus Christ means a “turn around”, a fresh start.
When you’ve been given a fresh start it is easy to be gracious to others.
If you call yourself a Christian you should be known to be a gracious person. There’s no faking it.
