The importance of the heart is to be genuine.
Not just the external appearance.
To Clean our talks. (avoid gossip, bad words expressions, etc. . .)
Traditions - are handled down and obeyed but not really the law of God.
The Pharisees ask a deceptive question (not sincere/genuine) to capture Jesus...
As believers we should not take our parents for granted but the pharisees taught that it is ok not to help your parents if you help others or the church. Jesus emphasize the Ten Commandments that taught us to Honor your father and mother. How could you follow the traditions of not washing your hands before you eat but not follow the Law of God?
18 If someone has a stubborn and rebellious son who does not obey his father and mother and will not listen to them when they discipline him, 19 his father and mother shall take hold of him and bring him to the elders at the gate of his town. 20 They shall say to the elders, “This son of ours is stubborn and rebellious. He will not obey us. He is a glutton and a drunkard.” 21 Then all the men of his town are to stone him to death. You must purge the evil from among you. All Israel will hear of it and be afraid.
Ezekiel 33:31 My people come to you, as they usually do, and sit before you to hear your words, but they do not put them into practice. Their mouths speak of love, but their hearts are greedy for unjust gain.
Some people like to hear stories made by man. But NOT interested to listen to God's words. People in reality like entertainment.
Ephesians 5:3 New International Version (NIV)
3 But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God’s holy people.
Luke 11:39-40 New International Version (NIV)
39 Then the Lord said to him, “Now then, you Pharisees clean the outside of the cup and dish, but inside you are full of greed and wickedness. 40 You foolish people! Did not the one who made the outside make the inside also?
The word of God - the truth will set us free.
2 Chronicles 26:16 But after Uzziah became powerful, his pride led to his downfall. He was unfaithful to the LORD his God, and entered the temple of the LORD to burn incense on the altar of incense.
Uzziah start as humble and excellent, in other words he is God-dependent. God provided for all his needs. God blessed Him so much. But he became prideful, and it's rooted from being so self-confident and lack of thankfulness.
Thus, as believers, we should always remember that what we have all comes from the source of all - our God. We need to humbly say "thank you" and not be in so much pride. Because, PRIDE will not lift us up but pull us down.
