1. I am sending an angel ahead of you (20-23)
God promised to Abraham the land of Canaan (Ge 15:18-21). It was already populated with powerful and wicked nations. God promised his angel, who bore his Name-his character, authority, and power-would clear the way. The people only had to trust and obey. In the same way, we follow Jesus, trusting and obeying him.
2. 'I will…' (24-33)
The main danger of the Canaanite peoples was not their armies, but their idols. To combat their corrupt practices, God's people should demolish the idols. But that was not enough. A good offense is the best defense: 'Worship the LORD your God.' If God's people focused on their own God, God would bless them. Note the repetition of 'I will...' in verses 25-33 (9x), showing God would do everything; he always keeps his covenant. All they needed to do was obey and worship the LORD. The LORD is our God too and has given us everything in Jesus.
Application: Father, you are worthy of worship because of who you are and all you have done for us in Christ Jesus. Help me worship you.
One Word: Let us worship the LORD our God
