Hebrews 8:12 For I will be merciful to their unrighteousness, and their sins and their lawless deeds I will remember no more.
If we start to think about what is actually sinful in our lives we may be in for a huge shock! All unrighteousness is sin! Everything that is contrary to the law of God is sin!
This gives us a considerable problem in that we cannot get over that barrier unless we have a Saviour who is able to lift us over it!
God is not just merciful and graceful, but merciful and graceful enough to overcome any sin that we have committed in our past – so long as we are willing to bring it before Him with all honesty!
