Getting hung up on apologetics may cause someone to give up on converting someone. Only the Holy Spirit actually converts. A person has an "aha" moment, and realizes that Jesus is God and that the one, true, holy, catholic and apostolic Church is the Catholic Church.
This "aha" moment may come from hearing or discussing apologetics, but in the opinion of my learned friend, most likely only suffering brings people into the Church.
He may be correct. We must preach the Gospel, the Good News of the redemption brought about by Christ, the God-Man, but whether someone converts is entirely up to his free will.
I pray for those who may want to convert but are finding it difficult to leave all behind in order to follow Christ.
