There are limited opportunities for people to accept the gospel. This isn’t something that people can put off until later as later is not guaranteed. At the same time, I can’t stress this enough. YOU are not going to save anybody. Not a single person ever in your lifetime. GOD is the one that saves someone and they have to make that decision on their own. It doesn’t matter if you beat them over the head with a Bible to repeat your sinner’s prayer just so you would go away, it’s not up to you to tell anyone if they’re saved or not. You are only responsible for sharing your testimony and the gospel and answer any questions you can. You won’t even know your entire life if something that you said turned that light switch on unless you’re lucky and they tell you.
