The final words of Moses to the Israelites before they entered the Promised Land are captured in the Song of Moses in Deuteronomy 32:1–43. It highlights themes of remembrance, rebellion, and reliance on God as the rock of Salvation. This sermon connects the themes of Moses' final words and Joshua's leadership to the concept of spiritual warfare. It stresses the need for modern believers to prepare for battles against spiritual adversaries, drawing parallels between the Israelites' physical battles and the spiritual struggles faced today. The importance of putting on the armor of God is emphasized, as believers are reminded to rely on God's strength rather than their own.
