The following comment is inspired by Matthew 5:20. All nations have groups of people who governs,teach,enforce laws and standards to it's people. Israel is not different. The Scribes and Pharisees are apart of Israel's
governing establishment,who helps guides and governs the people. What makes us justified before God is if we obey the laws of God,the same if we obey the laws of the land. Notice,Jesus is not rebuking the Scribes and Pharisees for being scribes and pharisees,but
for the corruption that have took over under their watch,and the unbrief and self righteousness that they have in their hearts against God. The Scribes and Pharisees are not the only ones guilty of these sins,it can be found in the Christian establishment
today. Lord help us to repent.
