According to Scripture, our eternal destiny IS sealed forever by faith. So, if that means we have been given the faith of Christ when we believe in Him, we ARE sealed with the Holy Spirit until the day of redemption and we are forever HIS. I think far too much is being made of the words "in" and "of". If you looked at an online parallel Bible at Galatians 2:20, it's about 50/50 for "faith OF Christ" and "faith IN Christ". Of course, the translators often use words in English that best impart the original languages' meanings and in order to do that they add extra words. The KJV designates added words by using italics, and it is understood that it means the word was "added by the translators". This ongoing nattering over the right word seems to have lost the point.
If people such as Copeland deduce they are "little gods" because they have the "faith of God", then that is their own peculiar interpretation, outside of Scripture. We certainly have other Scriptures that adequately disprove such an UN-orthodox belief. And that really IS the special quality of believing the Bible is our rule of faith. Accepting sola Scriptura essentially means that all truth claims for the Christian faith must be measured BY Scripture. It does NOT mean that there are no other resources available to a Christian who seeks to understand his faith - including those gifted to the church in the forms of teachers, pastors, etc. Believing in the sufficiency of God's word places these people as subordinate to the scriptures and not the other way around as some religions do.
