"2"The teachers of the law and the Pharisees sit in Moses' seat. 3So you must obey them and do everything they tell you. But do not do what they do, for they do not practice what they preach. 4They tie up heavy loads and put them on men's shoulders, but they themselves are not willing to lift a finger to move them.
5"Everything they do is done for men to see: They make their phylacteries wide and the tassels on their garments long; 6they love the place of honor at banquets and the most important seats in the synagogues; 7they love to be greeted in the marketplaces and to have men call them 'Rabbi.'
13"Woe to you, teachers of the law and Pharisees, you hypocrites! You shut the kingdom of heaven in men's faces. You yourselves do not enter, nor will you let those enter who are trying to.
15"Woe to you, teachers of the law and Pharisees, you hypocrites! You travel over land and sea to win a single convert, and when he becomes one, you make him twice as much a son of hell as you are.
16"Woe to you, blind guides!
Self-righteousness leads to pride.
Holiness leads to love.
The fine line is where your heart is focused. If your heart wholly focused on God, then you walk the path of holiness, denying the self.
If your heart treasures things of the world more than God, then you walk the path of this world, a path of self-righteousness.
Which path do you walk? The fine line that divides it is not always easily seen. Be aware of where you are walking and why.
And it might be good to better understand what a phylactery is before you skip over the fine line.
Go in peace and go with God.
