Jesus did not preach eternal security! Jesus never taught that once a man accepted him he can never go back on it. I was listening to a famous preacher not to long ago saying that everyone on the earth is saved and no one will go to hell. He stated that Jesus' death was powerful enough to save everyone and so, we all are going to heaven. But the word of God never said that. Another problem with what he was saying was that he claimed eternal security teachers are not far from his teachings. You see, if we teach a person that they are eternally secure once they accept Christ and even if they denounce him, they are still saved, then we are teaching pretty much the same message as the enclusionists. Jesus said that many that think they are saved are not! He said that many may call him Lord and claim him and still they will go to hell. He even said that people will have performed miracles in his name and he will still turn them away because he never knew them. Sounds like church folks to me! And I'm sure they were taught eternal security as well, because they believed that they would be saved!
I have a problem with people that teach things that are not clearly stated in the Word. If i can't turn to it the Word and read it for myself, then I'm not gonna risk my eternity on it! If Jesus said everyone that once called him Lord is not going to make it in, then that's what I'm going to believe. I just can't believe that a person that denounces Christ, turns away from God and chooses the world over his Kingdom is fit for God's Kingdom. Jesus even said that the man that turns around and takes his hand off the plow is not fit for the Kingdom. So, how can someone just decide they don't want God's way, Jesus' words, or would rather live in sin, and they still make it in because of eternal security? The only way you can be secure in God is to know Jesus and endure til the end! The Word says those that endure til the end shall be saved, not those that turn their backs on God. If you don't know him, then you don't know where you stand with him. My bible teaches that if we are to be with him, then we must work out our own salvation with FEAR AND TREMBLING! That doesn't sound like someone that has it made, but that sounds like a fear of God and a fear of hell fire and damnation if we turn our backs on him. We all make mistakes, and we may even fall into sin. We don't do everything right and we are growing daily. Those things are understandable. But woe unto the person that turns their back on God totally and chooses to live after the flesh and not serve God any longer. There is not a scripture guaranty that you will make it into heaven in this state. If you accept Christ, then you will serve him. You cannot serve two masters and you will not turn your back on the one you love. So, if you love him, you will obey him. And if you want to be eternally secure, then you better do what his Word says. The real problem is not whether or not a person can lose their salvation, but it's whether they ever really were saved in the first place!
