Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you
Scripture tells us in many places, that regardless of what thoughts and/or feelings we might experience, our 'conscious will' self, or soul, can choose to forgive those who've sinned against us, which as psychology has shown, provides many healing benefits for us. But, this can be VERY difficult to do, especially when we've been unfairly treated . While God's Word says vengeance is God's, our 'old-self' would love to see those people who've hurt us, suffer in return. However, when we pause and reflect on what the Apostle Paul said in Romans 7:20, that when he did the things that he didn't want to do, it wasn't 'HE' (his 'new man/new self' as a Christian) that did it, it was the sin ('old man/old self' as a non-Christian) living within him that did it, we have reason to forgive. Why? Well, perhaps like Paul, those people who've hurt us, didn't want to do it either. So, it wasn't 'THEM' (their 'new man/new self' as a Christian) that did it either.
