POINT 1: VALUES

Joshua 24:15 NIV 

But if serving the LORD seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your ancestors served beyond the Euphrates, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the LORD.”

POINT 2: VOLUME 

Joshua 6:10 NIV 

But Joshua had commanded the army, “Do not give a war cry, do not raise your voices, do not say a word until the day I tell you to shout. Then shout!”

Galatians 5:22 NIV 

But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, 23 gentleness and self-control. Against such things there is no law. 

POINT 3: VOW 

Joshua 1:3-7 NIV 

I will give you every place where you set your foot, as I promised Moses. 4 Your territory will extend from the desert to Lebanon, and from the great river, the Euphrates—all the Hittite country—to the Mediterranean Sea in the west. 5 No one will be able to stand against you all the days of your life. As I was with Moses, so I will be with you; I will never leave you nor forsake you. 6 Be strong and courageous, because you will lead these people to inherit the land I swore to their ancestors to give them. 

7 “Be strong and very courageous. Be careful to obey all the law my servant Moses gave you; do not turn from it to the right or to the left, that you may be successful wherever you go.

Joshua 26:15 NIV 

But if serving the LORD seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your ancestors served beyond the Euphrates, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the LORD.” 

Genesis 12:7-7 NIV 

Abram traveled through the land as far as the site of the great tree of Moreh at Shechem. At that time the Canaanites were in the land. 7 The LORD appeared to Abram and said, “To your offspring[a] I will give this land.” So he built an altar there to the LORD, who had appeared to him. 

Ecclesiastes 5:4-6 NIV 

When you make a vow to God, do not delay to fulfill it. He has no pleasure in fools; fulfill your vow. 5 It is better not to make a vow than to make one and not fulfill it. 6 Do not let your mouth lead you into sin. And do not protest to the temple messenger, “My vow was a mistake.” Why should God be angry at what you say and destroy the work of your hands? 

Matthew 18:19-20 AMP 

“Again I say to you, that if two [a]believers on earth agree [that is, are of one mind, in harmony] about anything that they ask [within the will of God], it will be done for them by My Father in heaven. 20 For where two or three are gathered in My name [meeting together as My followers], I am there among them.”
