You don’t need to talk to unbelievers to try to convince them about creationism versus evolution. Evolution neither saves a person nor condemns them. The thing that saves or condemns a person is whether they know what Jesus did or not.
John 3:18 (NKJV) He who believes in Him [Jesus] is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
Showing someone what the Bible says about creation is something you would talk to a believer about. There’s nothing wrong with having that discussion, but it’s almost always going to serve as a distraction if you’re trying to witness to an unbeliever. It’s a distraction from the real point that they need to believe.
Despite the fact that it may sound interesting to both you and them, what is the point if you win them over on creationism and they don’t know Jesus? Furthermore, you don’t want to portray to them that “creationism versus evolution“ is their problem, because it’s not. You can believe in evolution and still be saved if you believe in Jesus. In fact, it may not be a bad thing to let them know that. It’s not a barrier to entry.
Endless arguments about the age of the earth, whether man evolved from a single cell or not, and layers of rock and ice aren’t how people get saved. It’s not that we shouldn’t have those conversations, but those things should not be used to try to win over an unbeliever.
1 Timothy 1:4 (NKJV) …nor give heed to fables and endless genealogies, which cause disputes rather than godly edification which is in faith.
For what it’s worth, at Reform Church we believe that everything produces after their own kind, the way the Bible says. We believe that God created man in His own image, and despite sin and death having come into the world, man has been producing after his own kind ever since. Things can change to a certain extent, but everything stays within its kind. And science will never be able to tangibly demonstrate otherwise (and it still hasn’t). The “links” between kinds will always be missing.
If you’re waiting for most scientists to say that God created everything, don’t hold your breath. It turns out, that when you’re ONLY looking for a material reason to explain the universe, you’re probably going to come up with a material explanation. Who knew? Yet we know better, but let’s stick to telling people about Jesus if we want to get them saved.
