True or False?
When someone says they want to become a saved Christian and follow Christ, , they don't always mean it. Some just say it to patronize you, that is to say, make you feel good by saying something they don't mean. Now, everyone doesn't do that; a lot don't, but you always want to be prepared for those who do. Only the Lord knows who is truly saved and who is not; it's not for us to judge. We can, however, try to notice signs that point to the fact that they might be false. If someone has truly decided that they want to be a saved child of God, they will do some things they haven't been, and not do certain things they have. For example, if they want to be closer to God, they will read their Bible, and if they don't have one, they'll buy one. You can kind of coax them gently to read the Bible, and if they do, you're fine, but if they don't, well, actions speak louder than words. They might not be a real Christian.
You can't expect people to change overnight. You also can't expect them to have the same convictions you do. If someone has recently come to Christ, there might be some unchristian things that they've been doing, inappropriate things they might read, watch, say, or do. Things they really should change about their lives. Now, that doesn't necessarily mean their not a Christian, just that they haven't yet realized that what they've been doing is wrong. You shouldn't immediately assume that they're faking it if they don't instantly change. You also shouldn't try to change them-that's God's job, not yours. You should trust but verify. Trust that they're truthful when they say that they've come to Christ, but try to verify that they are, too. It sounds tricky, but if they are false, it will be pretty obvious after awhile.
Look for certain signs. If you're a new Christian, you're going to have questions, so they should. If they don't ask you any questions, you should verify by saying something like, "Do you have any questions?" If they do, and they just haven't said anything, that's fine. If they don't, maybe they just don't, but they will. On the other hand, it might mean that they're not really a Christian. Again, you should trust them fully, but always be on your guard in case something doesn't seem right.
You don't know who's saved and who isn't, so don't try to. Just do your job and try to help them the best you can. There is a good chance that they are truthful, so just stay calm. Let go of your worrying and trust God. It's His job to take care of His children, and He's not worried, so you shouldn't be, either.
The world of evangelism can be a dangerous one, because you can't see into everyone's true heart. But if you go into it backed up with facts and armed with the, "Armor of God", as it says in Ephesians 6:13, you'll be much stronger and prepared to face anything that may come your way. That way, you will stand firm and never waver in your faith in the Lord. If the "Glory of the Lord is your rear guard", you will never fail Him. Never.
