I fast twice per Sabbath, I pay a tenth of everything that I aquire.
Luke 18:12
The Pharisee was very impressed with himself and felt God should be as well. Outlining good deeds, he sought to qualify himself as a very righteous individual.
Fasting twice a week was not required in the law. There were required fasts, but not with this regularity. The tithe was the law, though the Pharisees tended to make paying it an art form. They would bend over backwards to ensure a tenth of absolutely everything was paid.
Heavenly Father, thank You for the abundant gifts You have blessed us with. Our obedience to Your commands is only a just response to Your goodness. We are not righteous and are nothing on our own. But I praise You for Christ! By Him alone we may come to You and live in His righteousness. To be righteous is a wonderful blessing, but it is nothing we could ever earn, and wholely trust in Christ for it. Thank You! In the Name of the Lord Jesus Christ I pray and praise You, Amen.
