Some people call this change of heart spiritual transformation. God calls it being born again. When we are born again, God changes our evil, impure hearts into clean, pure hearts that are suitable homes for him.
See below to understand the characteristics of each kind of heart:
It is worth noting that all of the characteristics of a clean, pure heart are essentially invisible, except to the born again person and God who knows our hearts. It is also true, however, that the overflow of our hearts is evident to others as good works/deeds which include, but are not limited to, the following:
It must also be said that people in whom these characteristics are present have God’s name (i.e. character) and spiritual laws written on their hearts. This is how they qualify for status as a New Covenant disciple. This also is the evidence of being born again.
But, the heart is not always a positive place as we see in the following scriptures:
God characterizes evil, impure hearts as unrighteous.
Evil impure hearts fear that they will be punished because their religious activities do not satisfy God’s standards of righteousness and that they will spend eternity in hell.
Evil impure hearts are not united with the hearts of others.
Religious people are self-righteous because they obey religious laws, but they are unrighteous with respect to God’s spiritual laws written on their hearts. (Whenever the bible refers to religious people as being righteous, it actually means they are self-righteous.)
Hearts with these characteristics are found in Old/First Covenant religious people.
In God’s opinion, religious people have evil, impure hearts because they show affection for (i.e. idolize) false prophets and trust their words/writings.
Unlike clean pure hearts, which are essentially invisible to the public, evil, impure hearts have many ways of breaking out in ugly, destructive, public ways. Here are a few examples of characteristics that may be found in people with evil, impure hearts:
Greed, selfish ambition, argumentative, jealousy, fits of rage, divisiveness, envy, arrogance, disrespect for other cultures, disrespect for authority and law.
Little or no mercy or compassion for the poor, downtrodden.
Quick to anger and slow to forgive.
Potential to display physical violence and verbal abuse.
Fanatical displays of self-righteousness in politics and secular movements.
Calling these characteristics evil will seem like an unreasonable overstatement to most people. This is to be expected, perhaps, given the common, public association of evil with satan, the devil and demons. His use of the term may be more acceptable if we remember three facts:
Because the characteristics of an evil, impure heart are inconsistent with God’s character (i.e. name), it must be said that people in whom these characteristics reside are not New Covenant disciples. It must be said that God’s spiritual laws are not written on their hearts. Rather, they are Old/First Covenant religionists who observe religious laws. This is true for practitioners of any religion (including Jews, Christians, and Muslims) and for those who practice no religion at all. It is also true for people who who do not even believe in God because even unbelievers still observe their own personal laws, household laws, civil laws, institutional laws which are all created by people who may or may not claim to have been inspired by God when they created those laws.
What people who make laws of one kind or another claim about the source of their inspiration makes no difference to God and should not be a matter of concern for anyone who follows the laws which they have created. Sometimes these human laws are consistent with God’s spiritual laws, but generally they are not.
