While Level 1 helps to encourage community and charity, and Level 2 provides recognition for belief that there is a Supreme Being or Creator, higher levels take into account a persons' beliefs about that Supreme Being or Creator and correspondingly, revealed truth.
Access to Level 2 and higher levels can come though accumulating halos oriented towards reaching those levels, in cases where the user is not sure of what they believe, or it can come through acknowledgement, implying a person is aware of certain revealed truths and confident in what they believe.
In the case of access obtained through halos, for example, those on Level 2 who wish to access Level 3 would likely benefit from learning more about salvation history, knowledge which would be obtained by studying Jewish history and what is generally known by Christians as the Old Testament. In addition to Scripture itself, several resources are available for obtaining the appropriate credits, such as "The Bible - The Epic Miniseries DVD," and "The Bible Timeline: The Story of Salvation" by Jeff Cavins, Dr. Tim Gray and Sarah Christmyer.
Users who can be found on Level 3 believe that the God of the Israelites is the true Supreme Being and Creator, as opposed to many gods, a less personal form of God or another description altogether. They accept that God has intervened directly in human history, and in accordance with such intervention, demonstrated His love for humanity, helping to restore a fallen state where sorrow and suffering tend to predominate. In demonstrating this, they acknowledge that knowing about Him and the truth He has revealed is of vital importance, potentially leading to a better relationship with Him and with each other, a path to greater joy and abundance.
Of note, theological advancement that starts with recognition of the God of the Israelites over other descriptions of Him is not to discredit the many achievements in social justice that have been accomplished through other faiths and cultures. And yet, this is not to suggest that social justice is the main issue.
While Islamic cultures, for example, are filled with many uniquely beautiful attributes, such as architecture, calligraphy, dress, cuisine and customs that show reverence to God, and while the Koran contains many wise teachings that can help inspire and uplift the individual, helping to create a lawful society, the cultivation of virtue and the establishment of peace, some of the "truths" with regards to God's nature are considered to be inaccurate or untrue. This inaccurateness with respect to God's nature also exists in the Mormon faith and that of the Jehovah's Witness.
Nonetheless, all of these communities contain many beautiful characteristics and it is hoped that these will be preserved for the betterment of culture and society. However, just as if someone described your best friend inaccurately and you hoped to correct them, it is necessary that an accurate understanding of God's nature is taught and upheld. Likewise, with regards to theological truths concerning God's nature, points of demarcation are necessary as one advances through theological levels within Pure Heart Culture.
