Our world is full of head religion without a heart. Jesus Christ said it perfectly,
“This people draw near unto Me with their mouth, and honor Me with their lips; but their heart is far from Me.” (Matthew 15:8)
A person that is “Born Again” and right with God is ruled by their heart. Soon after anyone becomes a transformed person, the head and the heart will experience a certain level of conflict. The head says, “I’m the boss” but the heart says,“No you are not, He’s the boss,” and the war is on. This is where the old Methodist would say,“You need to be sanctified.” Sanctification is death to the head and holiness to the heart.
The head can know great facts about truth and Christ, but the heart must be under His mastery before you become a transformed Christian. The Bible says it plainly,
“For as he thinks in his heart so is he.” (Proverbs 23: 7a)
The heart is where the claims of Jesus Christ are established. Until the heart is involved in total surrender and all life is on the alter that soul is lost.
