"The heart is deceitful above all things!" This is such a profound and countercultural statement. It's also one of the many reasons why I hate the vapid, and all too common, excuse for unjustifiable behavior: "the heart wants what the heart wants." Blech!
Galatians 6:9-10 NKJV And let us not grow weary while doing good, for in due season we shall reap if we do not lose heart. Therefore, as we have opportunity, let us do good to all, especially to those who are of the household of faith.
