1. These are the commands, decrees and laws the LORD your God directed me to teach you to observe in the land that you are crossing the Jordan to possess, 2so that you, your children and their children after them may fear the LORD your God as long as you live by keeping all his decrees and commands that I give you, and so that you may enjoy long life. 3Hear, O Israel, and be careful to obey so that it may go well with you and that you may increase greatly in a land flowing with milk and honey, just as the LORD, the God of your fathers, promised you. 4Hear, O Israel: The LORD our God, the LORD is one. 5Love the LORD your God with all your heart and with all your soul and with all your strength. 6These commandments that I give you today are to be upon your hearts. 7Impress them on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up. Deut 6

2. 44 “The kingdom of heaven is like treasure hidden in a field
44 “The kingdom of heaven is like treasure hidden in a field. When a man found it, he hid it again, and then in his joy went and sold all he had and bought that field.
45 “Again, the kingdom of heaven is like a merchant looking for fine pearls. 46 When he found one of great value, he went away and sold everything he had and bought it. Matthew 13

3. 23 Above all else, guard your heart,
for it is the wellspring of life.

4. Ezekiel I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your impurities and from all your idols. 26 I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh. 27 And I will put my Spirit in you and move you to follow my decrees and be careful to keep my laws.

5.  19 Therefore, brothers, since we have confidence to enter the Most Holy Place by the blood of Jesus, 20 by a new and living way opened for us through the curtain, that is, his body, 21 and since we have a great priest over the house of God, 22 let us draw near to God with a sincere heart in full assurance of faith, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water. Hebrews 10:22

6. Proverbs 2719 As water reflects a face,
so a man’s heart reflects the man.
43 “No good tree bears bad fruit, nor does a bad tree bear good fruit. 44 Each tree is recognized by its own fruit. People do not pick figs from thornbushes, or grapes from briers. 45 The good man brings good things out of the good stored up in his heart, and the evil man brings evil things out of the evil stored up in his heart. For out of the overflow of his heart his mouth speaks. Luke 6

7. Mark 7:17-23
17 After he had left the crowd and entered the house, his disciples asked him about this parable. 18 “Are you so dull?” he asked. “Don’t you see that nothing that enters a man from the outside can make him ‘unclean’? 19 For it doesn’t go into his heart but into his stomach, and then out of his body.” (In saying this, Jesus declared all foods “clean.”)
20 He went on: “What comes out of a man is what makes him ‘unclean.’ 21 For from within, out of men’s hearts, come evil thoughts, sexual immorality, theft, murder, adultery, 22 greed, malice, deceit, lewdness, envy, slander, arrogance and folly. 23 All these evils come from inside and make a man ‘unclean.’”

8. 22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness and self-control. Against such things there is no law. 24 Those who belong to Christ Jesus have crucified the sinful nature with its passions and desires. 25 Since we live by the Spirit, let us keep in step with the Spirit Galatians 5
8 Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things. Philippians' 4
