Deuteronomy 6

2 The main purpose of the Law was to instill the people with a profound respect for God. But at the same time we benefit by living the way God designed us to. The various details of the Law compel us to live a healthy life and encourage solid and peaceful relationships. If the entire nation follows God, He will show them favor and protect them even when they are attacked.
4 This is the core statement of belief: God (the "I AM") exists, He is our God, and He is the single, unique God. This statement rules out atheism and pantheism, and confirms that God can be known on a personal level.

This verse is called the shema after the Hebrew word "hear." It is the primary creed of Israel.

5 Our personal relationship involves complete devotion to God. Our emotions, our thoughts, and our deeds are all to be hooked into our love for God.
6 The commandments are to be memorized.
7 Knowing and obeying the Law was not merely a "personal decision." Parents were to make sure that their children were fully aware of how God desires them to behave. Such training is a full time activity and involves verbal communication as well as day to day living examples.
8 Some people take this verse literally and wear little verse boxes on their forehead or strapped to their arm. The boxes strapped to the arm are called phylacteries (Mat 23:5). Christian t-shirts or necklaces with crosses serve this purpose for Christians. The use of visible symbols can be helpful, but the important idea is that we live in such a way that our devotion to God is evident to everyone who sees us.
9 It is also important to devote our houses to God's work. It is appropriate to decorate the exterior and interior of our houses to reflect our love for God. When God gives us stewardship of property and possessions, we are to use and maintain them for the purpose of glorifying God.
12 It seems to be human nature to cry out to God when we are in trouble and then forget all about Him when things are going well. Even worse, God may help us through a bad time and when the situation improves we feel it was our own effort that changed things around. When we stop depending on God then we displease Him. We must remember that even when life gets easy we still must depend on God for everything.
13 God is the only one who should be revered as deity and worshiped. We are not to make any vows to any other god.
15 God will not share the divine stage with anyone because He is the only God. He is extremely insulted when people give humans, idols, or ideas the credit for works He has done, or consider them to have divine authority.
16 God does not need to constantly "prove" His authority for us. He has given us ample evidence through the Bible, creation, and works in our own lives. It is very dangerous to have the attitude, "God has helped me before, but what has He done for me lately?" Our faith in God must not waver when situations become bad. Even if we do not see how God is working in a given situation, we must trust that He is.
18 Not every possible situation is spelled out in the Law. But the Law becomes a guide even in "new" situations. God has given us great reasoning ability so that we can do what is right no matter what happens in the world.

The Israelites were promised to enjoy God's favor and land when they were obedient. Christians are promised eternal life with God.

20 When an Israelite was asked, "Why do you believe?" he was to have a ready answer: "God had freed His people from slavery with astounding miracles and has given them a good land of their own to live in. We obey God because we know He is God and out of gratitude for what He has done for us." Likewise, Christians can recount how God freed us from our sins through Jesus and is currently leading us to our eternal home with Him.
25 When we obey God we do what is right.
