Some Confuse the Meaning of the Words "Faith" and "Grace"
I occasionally run across Christians that mistakenly use the words "faith" and "grace" interchangeably. It could be argued that this has led to a large number of errors in the church including the carnal Christian heresy. This error asserts that faith is a mere perception of and assent to the facts of Christianity, without allegiance, love or gratefulness to God (all of which are thought by them of as additions to the gospel) But it must be remembered that faith and a grateful heart that desires to obey God are all impossible apart from regenerating grace. We are not saved because of a grateful, obedient faith but saved UNTO a grateful, obedient faith. All spring from a heart renewed by God (Ezek 36:26; John 6:63-65, 37). Grace is not the reward for faith or obedience but the fountain from which they spring.
“Moreover the Lord your God will circumcise your heart and the heart of your descendants, to love the Lord your God with all your heart and with all your soul, so that you may live." Deut 30:6.
"Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh. I will put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances." - Ezekiel 36:25-27
