In the New Testament, Christian life is sometimes described with the same language used to describe war and battle (2 Co 10:3-4; Eph 6:10-18; 2 Ti 4:7). While this chapter is about physical war, the same principles can apply directly to our spiritual warfare.
War is inevitable for the Israelites. They will face enemies who are militarily stronger than them. The LORD their God reminds them not to be afraid. He is with them and he will fight their enemies to give them victory. Courage to face their enemies does not come from the size of their army but from the greatness and power of God. God promises victory. The battle is not theirs but God's (2 Ch 20:15).
God also gives direction on who should not go to war. This reduces the size of the army and deepens the nation's dependence on God in the time of war. God gives exemptions for those who have not enjoyed his blessings to go and enjoy them for a time. Those who are afraid are also sent home. When God sends the Israelites outside of Canaan for war, an offer of peace is allowed. But for battles in Canaan, the Israelites are not to offer any mercy. The LORD warns the Israelites that the Canaanites will lead them into idolatry. Therefore, the Israelites must not compromise with them.
Application: Lord, you are stronger than my enemies and my fear. Grant me courage and faith to face enemies and experience your victory today.
One Word: God is with you and fights for you
