From Scripture

                             Matthew 21:28-32, 
                             Honest obedience.
                             Jesus told of a man who asked his two sons to go work in his vineyard.  The first said, "No," but went anyway.  The second said, "Yes," but didn't go.  Which son did as the father asked?
                             The father in the parable is God.  The first son represents the outcasts of society.  They said "No" to God at first, but repented of their sins and changed.  The second son represents the Jewish religious leaders.  They said "Yes," but it was just lip service.  They followed rules rather than change their hearts.
                             Saying, "Yes, God, I believe in you," is not enough.  If we presume that the Lord will take us into Heaven just because we profess our faith, we will be disappointed.  Words are not enough.
                             True obedience is lived.  When we realize we are in a state of sin, we have two options.  We can say we're sorry, or we can show we're sorry by going to Confession, doing sincere penance and amending our lives.  Living as Jesus taught us is our way of "working in our Father's vineyard."
