Well written.
This is the angle which I'll come from - Grace.
I thank God for sending that helper, the Preacher who came to you while in the prison.
It's all about grace to shows how God loves us and won't give up on us.
He's promised never to withdraw His love from us when we ask for it. It's by this grace that we are saved.
Let's always express our gratitude to this merciful God whose love is incomprehensible.
