In Deuteronomy 20 - 22, Moses reminds God's people that we are not to be afraid or live in fear. We can rest assured and know that God is with us in every step of everything we face. We will have battles, but we also have God and He is mightier than anything we will face. God places high value on life, respect for life, and the dignity of others. God cares so much for His creation, He makes sure it is understood we are to respect the life of trees and birds as well. He reminds God's people to do the right thing and remain pure before God as God's chosen people - set apart for Him. God wants to remain with His people and they didn't have Jesus yet. God is supremely holy and pure and sin cannot dwell anywhere near that divine holiness. We have Jesus and Jesus wiped away all our sins to make us pure so we have the amazing privilege of abiding with God every second of every day if we choose to accept Jesus as our Lord and Savior.
