It is time for believers to stop confessing something that is absolutely unbiblical and detrimentally misleading to their own souls and to the souls of others. The Divine Truth is that, when believers continue to call themselves sinners saved by grace, their evil communication not only contaminates them and others but also grieves the Holy Spirit, which by extension means God our Father also is grieved (cf. Ephesians 4:29-30).
There are many patterns in the Holy Bible. However, many biblical patterns are not easy to recognize. Only when we are able to see that a spiritual truth stated in one part of the Holy Bible has been repeated in a similar fashion in another portion of the Holy Bible will we not only be able to recognize the process in the biblical pattern but also we will be able to discern what God wants us to learn from that pattern.
