This is a great quote by Abraham Lincoln but I also think taking away someone’s power, hope, and purpose may perhaps be an even greater way to test their character.
Oftentimes, though we may deny it, we do good things for the good we receive in return. There is nothing wrong with this but the true test of doing good is when nothing is received. To risk living rightly, going the extra mile, loving the unlovable and experiencing nothing but scorn, derision, rejection is a true test of who we are and why we do what we do.
To face loss, deprivation, spurning, even emotional, spiritual or physical death and still choosing to do the ethical, moral, honorable thing reveals our true motivation.
