No one is good except God alone (Mark 10:18)
"None is righteous, no, not one;
no one understands;
no one seeks for God.
All have turned aside; together they have become worthless;
no one does good,
not even one.”
“Their throat is an open grave;
they use their tongues to deceive.”
“The venom of asps is under their lips.”
“Their mouth is full of curses and bitterness.”
“Their feet are swift to shed blood;
in their paths are ruin and misery,
and the way of peace they have not known.”
“There is no fear of God before their eyes." (Romans 3:10-18)
And you were dead in the trespasses and sins in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience—among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind (Ephesians 2:1-3).
Christian, we were never good. We were not born good. Thanks be to God, He provided Someone to be good for us. He lived a perfect life by doing the things we cannot do. His name: Jesus.
You may not be that good, but Jesus is the true Righteous One who took our sin, made it His own, and now God calls us righteous.
For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God (2 Corinthians 5:21).
