Jesus had the same problem. Some accepted His message and many didn't accept His message. A student is not above His teacher.I'm for evangelism--the proclamation of the Gospel. What I disagree with is the idea that we can make other people Christians. I can't bring someone to Jesus, Jesus brings people to Himself. It's about understanding that God works through the Means of Grace to accomplish His purposes, the Church is the instrument through the Means are found--preaching the Word and administering the Sacraments--but as an individual it is not in my power or ability to make someone else believe. I can't make another person believe, I can't argue or debate or reason a person into faith--because faith isn't something that comes by reason, intuition, or argument; faith comes extra nos, from outside ourselves, as a supernatural gift of God apart from us.
I'm not going to make anyone a Christian by arguing with them, or trying to convince them through the use of rhetoric or reason. Evangelism, the proclaiming of the Gospel, is a very different thing than arguing a person into believing. If someone asks me about my faith, I am happy to share with them my faith and hope--but as St. Peter says it must be done with gentleness and respect.
The student is not above the teacher, but everyone who is fully trained will be like their teacher.
And Jesus made some fishers of men.
As I stated such work (not for our salvation or sake) but for the good of others in leading one to Christ for "their" salvation is a work of love. And is the Fathers work. Therefore lawful and good.
Each must call on the lord themselves as we can't convert people.
