‘It is not the beginning that is rewarded, but perseverance’ (Saint Catherine of Siena).
There is a very powerful proverb that says, ‘The road to hell is paved with good intentions.’ It is a serious warning not to falter on the good path that has been taken or that one wishes to take. Sacred Scripture also gives us similar admonitions, with different formulations. It is always a matter of exhorting us to perseverance and constancy on the path of God.
