‘I am the Lord, that is My name; I will not give My glory to another’ (Isaiah 42:8, NASB).
In the opening chapters of Exodus, we saw Pharaoh, the most powerful person in the world at the time, set himself up in opposition to God. In oppressing God’s people, he was taking on God himself. And God will suffer no rivals.
We therefore see, in chapter 14, God’s great victory over Pharaoh. In v18, God says that he will ‘gain glory through Pharaoh’. This is why God hardened Pharaoh’s heart: God wanted everyone to know of His great victory over Pharaoh.
The Egyptians worked out what was going on: in v25, they say let’s get away, the Lord is fighting for the Israelites.
Verses 30 and 31 are of central importance. In v30, the language of salvation is used: ‘the Lord saved Israel’. The result of this salvation? In v31, the people feared the Lord, and put their trust in Him and in Moses His servant.
Where do we place our trust? Many things other than God can seem glorious to us at times: success, money, power, strong leadership, political powers. But God will suffer no rival, including for our affections. We ought not place our ultimate trust in anyone or anything other than God.
