To err once or twice is being human. But conscious erring is an intentional flaw magnifying in effect the vulnerability of man to submit to constant temptations. Conquering his own weakness is his real battle.
Good deeds make a good man. Goodness is the consequence of justice evolving inside the soul of an upright man. Human beings are not perfect.
Mary Baker Eddy has this to say: "Truth is immortal; error is mortal".
What is the truth? The reality untainted with deformity. No minuses nor addition. It exists as a law, untouched and unconcealed.
Error is man's weakness. This is the truth. That man is not perfect therefore he flaws.
But we all have the chance to correct what is wrong. A good man knows his limitations and knows when to make amends.
Stick with the truth. It will set you free.
