“To convert somebody, go and take them by the hand and guide them.”
— St. Thomas Aquinas
Notice that St. Thomas Aquinas does not say drag them by the hand kicking and screaming. Mentoring someone in the Way of Christ requires humility, patience, love, and mercy. Generally speaking, people don’t tend to take in a message when it’s being yelled or they feel they are being forced or manipulated into believing.
It bears repeating, to guide someone to Christ on the path to holiness REQUIRES humility, patience, love, and mercy. True charity must be your motivation and gentleness, your method.
At the same time, you cannot give what you, yourself, are not already pursuing. If you are not praying, how then can you effectively teach someone how to communicate with God? If you are not participating in the sacramental life of the Church, how then can you speak with any credibility about the graces that are conferred? If you are not loving towards others, how can you show that both that you truly love God and that God truly loves? If you are not living an authentic Christian life, how can your life serve as an example of sanctification? In other words, as you guide disciples towards holiness, you, too, need to be working towards holiness.
