Integrity vs Obedience

Preface:
I have been in church my whole life. I have missed maybe 10 sundays of church in those 23 years. But I have never heard or read this parable before. I don't know why. Somehow I've always missed it.

S:- Matthew 21:28-32 - "What do you think? There was a man who had two sons. He went to the first and said, 'Son, go and work today in the vineyard.'
"'I will not,' he answered, but later he changed his mind and went.
"Then the father went to the other son and said the same thing. He answered 'I will, sir,' but he did not go.
"Which of the two did what his father wanted?"
"The first," they answered.
Jesus said to them, "Truly i tell you, the tax collectors and the prostitutes are entering the kingdom of God ahead of you. For John came to you to show you the way of righteousness, and you did not believe him, but the tax collectors and the prostitutes did. And even after you saw this, you did not repent and believe him."

O:- God, who knows everything, past, present and future, is more interested in the end result (obedience or disobedience) than the initial response. God knows what your answer will be before you give it. He also knows what your action will be before you take it. Far better to be the son who said no, but changed his mind, than the son who says yes, but changes his mind, or worse, never intended to obey in the first place.

A:- Let my yes be yes, and my no be no. Becoming a man of integrity is all about backing up my words with my actions. And letting my answer be yes and my actions backing that up is the ultimate response. Next in line is my answer being no, but my actions being yes. God and I can work on my integrity in the future. All God desires from me right now, is obedience.

P:- Lord, Help me to be the man of integrity you've called me to be. But more than that help me to be the obedient son. Better to be just a liar, than a disobedient liar. Give me courage and ability to do what you ask of me.
