It's Impossible To Believe In Your Mind But Not Your Heart

Romans 10:9-10 “That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.”

Someone made the following image, which contains heresy...

Beware Of False Knowledge,
Which Is More Dangerous Than Ignorance

There are three columns above, the first two of which are LIES!

It Is Impossible To Believe In One's Mind, But Not Your Heart

In the first column, to the left, it shows that you can have “HEAD BELIEF ONLY” (or, “MENTAL”). Dear reader, that is IMPOSSIBLE!!! You cannot “BELIEVE” with your mind, but not your heart. I once read a heretical tract by Pastor J. Vernon McGee (1904-1988) titled: “Missing Heaven By 18 Inches” (i.e., the distance between your brain and your physical heart). Although I like Pastor McGee and support his ministry, in this regard he taught blatant false doctrine.

The “heart” of which Romans 10:9-10 speaks is not your physical heart, which is a muscle about twice the size of your fist that pumps blood. Your heart is a part of your brain, located somewhere in your head. So the whole notion of being able to believe with your mind, but not with your heart, is ridiculous, both biblically and scientifically. The man who believes on Jesus Christ with his mind has also believed in his heart as well. You cannot trust Christ with your mind, but not with your heart. The very idea is very confusing to people. Your heart is your subconsciousness, the real you. When thoughts enter into our mind, whether good or evil, we must analyze those thoughts to decide whether to reject them, or to accept them, the results of which are stored in our heart and form our character (2nd Corinthians 10:5-6).

Having said that, it is possible to have knowledge in one's mind about how to be saved, and yet not believe that knowledge, but this is not believing. There is no faith involved. Moses preached the Gospel to the Jews in the Wilderness of Zin for 40 years the Bible says in Hebrews 4:2, but they did not have faith in the Gospel and perished in their sins. Those Jews could have told you how to be saved, but they themselves did not believe. Sadly, they all went to Hell to pay for their own sins, since they rejected the coming Messiah's blood sacrifice as payment for their sins. There are billions of lost sinners who are familiar with the Gospel of Jesus Christ. They have heard the Gospel their whole life. Yet they won't come to Christ to be saved (John 5:40).

Being Saved Does Not Guarantee A Changed Life

The second column in the chart above also contains heresy! Just because one is saved does not guarantee that there WILL be fruit in that saint's life. It is possible to live in the Holy Spirit (i.e., be saved certain - Romans 8:9; 1st John 3:24), and yet refuse to walk in that same Holy Spirit (Galatians 5:22-25). In other words, you CAN be saved but still live like the Devil, if you so choose. God will convict every saint that sins and chastise us. If you can commit sin without any conviction whatsoever from the Holy Spirit, it is only because you don't have the Holy Spirit and are not truly saved (Hebrews 12:6-8). God is not an absent parent.

Partial Faith In Jesus Plus Works Equals Damnation

The third column in the chart above is accurate. I encourage you dear friend to question everything, which is biblical according to 1st John 4:1, “Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.” That is, think objectively using the Word of God as your benchmark, against which to compare everything.

Romans 10:9-10 teaches that we are saved by believing, and with our mouth we confess because we are saved. But we ought never base any doctrine on a single passage of Scripture. As a general rule we should never interpret an obscure passage of Scripture which contradicts a clear one. Romans 10:9-10 doesn't mean that you must confess to be saved, which would contradict the entire Gospel of John, which simply  teaches to just BELIEVE ON JESUS. John 6:47, “Verily, verily, I say unto you, He that believeth on me hath everlasting life.”
