Isaiah 43:10-13 - Apart from me there is no saviour

43:10,11

We get several features of God’s people here. First, we are His witnesses. It is our job to bear witness to the Lord. Then we are His servant, chosen by Him,. Notice the God focus of all this.

The purpose is that may know and believe the Lord. That we may understand just who the Lord is, His absolute sovereignty.  He is the only God, and the only saviour

43:12

This gets us to the heart of the matter. “I have revealed and saved and proclaimed -  I and not some foreighn god among you”. Israel’s great failing was to think that other nations or other gods would save her, rather than trusting in the Lord. Now see what God wanted them to know, and wants all of us to know. He is the one who saves us. If anyone goes to God in repentance and faith they will be saved, and this is the message that the gospel proclaims. All men know that there is something wrong, all are looking for a means of salvation, but they look in the wrong place. 

Those who are saved by the Lord are His witnesses, we experience being saved and we are meant to say to the world that the Lord has saved us, and that He is the only way to salvation.

43:13

“No one can deliver out of my hand”. When someone trusts in the Lord they are completely secure in that salvation. Why not? Because it is the Lord who has done this, He is the one who has acted, so no one can reverse it. This is the sovereignty of God. Does this mean “once saved always saved”? Not in the sense that some mean it, not in the sense that you can do what you like and it doesn’t matter. Not in the sense that it doesn’t matter what we do with our lives, that is completely unbiblical. But we are completely secure in our salvation.
