Many people choose to believe the gospel and many choose not to. Before they can make a choice they need to hear the gospel. That is the job of Christians. Jesus said "Go into all the world and proclaim the gospel to the whole creation." I imagine that you've seen some teenagers who were brought up in church attending families walk away from Christianity for a time - perhaps even permanently. That's making a choice to reject the gospel that they've heard.
I was one of those kids and it turns out that they were too busy telling there own stories instead of encouraging one to read the bible, they would recite a few lines and then go on a humourous and often made up parable involving themselves which did sound 'nice' at the time but it just didn't have any impact on me because I had yet to actually read the Word myself.
You can't just grab unlearned people and sit them down in a church, read a few lines from the bible that relates to their personal experience and expect people to become believers. Laying on of hands and praying over people had more of an impact for me at a Pentecostal but I had already been absorbing the Word for years by then, the church did wake up the Spirit in me and opened my eyes so I thank God for sending his saints for me...
Now I can go to any church and it all makes better sense after having read the Bible, but as I said before the opposite doesn't really impact too many people.
I would have found it humbling if before, a preacher were to have said "please don't take my word for it, I encourage all young and old to read the Word for yourselves because I cannot possibility explain it all in all it's glory so please, families, hold bible studies with your kids and encourage them to read it in their spare time"
IMO it would have possibly helped rather than sitting in a pew and doing all that stuff that confused me.
Once I went to confession and I didn't know what sin was and he said "have you stolen anything?" and I lied and said that I stole a pencil :/ I think that's also the time I got locked inside the confessional and I couldnt open the door and the priest had to open it up for me and I was like "your not suppose to see me dont look!" lol
