We have a great need to rely on the fact of human goodness.
Sorry, but believing in lies is not what we need. What we need, rather, is the truth.
The truth is, "the heart is deceitful above all things, and desperately wicked". The truth is, "there is no one who does what is good". The truth is, "all of our works of righteousness are putrid rags". The truth is the Fall, mankind is sinful and wicked, we have all fallen short of God's glory, we have all sinned. We are not good.
In our daily life, we encounter people who are angry, deceitful, intent only on satisfying their own needs. There is so much anger, distrust, greed, and pettiness that we are losing our capacity to work well together. Many of us are more withdrawn and distrustful than ever. Yet this incessant display of what’s worst in us makes it essential that we believe in human goodness. Without that belief, there really is no hope.
Then there is no hope, for what hope is there in believing in a lie?
But there is hope in believing in the truth. The truth is, "while we were still sinners, Christ died for us". The truth is, "Christ Jesus came into the world to save sinners". The truth is, "Christ died for the ungodly". The truth is, through repentence and faith in Christ who love us and gave Himself for us, we can have forgiveness for our sins and eternal life.
Not through believing in fictions like what such good people we are. 'Cause we ain't.
