Until now discerning a particular vocation may well have been quite private and may not go any further.
However if you are hearing a new call that is strong and persistent then the next step can be to ask the Church to help in the discernment of a vocation. It may be to offer yourself for lay service or one of the other vocations.
It is suggested that you approach a priest or another person of faith who is known and trusted and ask them to help see the Lord’s hand at work in your life and to recognise the way in which He is guiding and calling you.
They will be able to help you decide the next step.
