Luke 3:12 “Then came also publicans to be baptized, and said unto him, Master, what shall we do?”
Here we see that a special class of people come to John. These were those among the Jews who were in the service of the Roman Empire. These in particular were the tax collectors. They would collect the customs, duties, taxes, and so forth of the Romans from the people of Israel. They were considered especially sinful by many of the Jews due to their cooperation with the Romans, and because of their tendency to over-tax so that they might supplement their income.
Heavenly Father, You have laid righteousness before us. By Christ we may live holy lives. It is all to Your praise. You are worthy! You alone are God and You alone have saved us. This life is not about us, but is all about You and Your glory. In the Name of the Lord Jesus Christ I pray and praise You, Amen.
