Today’s passage was written over 2500 years ago. Yet as I started to read I was impacted by Isaiah’s sense of humour. God’s people wondered if perhaps God did not seem to rescue them from their trials. They wondered if perhaps God had diminished in strength. They wondered if His arms are just too short? They wondered if His ears had become blocked. Perhaps the problem isn’t that God lacks power. He may just lack knowledge or interest in our problems.
But this isn’t the problem at all. Isaiah reminds us that this isn’t the God of the bible. God doesn’t have short arms or are His ears blocked. He can hear us just fine. This is the creator God.
The problem isn’t with God’s power, His knowledge or His interest. The problem is with our sin. Sin does not separate us from the love of God. But sin still can separate.
Sin separates us from fellowship with God, because at least at the moment of our sin, we no longer think alike with God.
Sin separates us from the blessings of God, because at the moment of our sin, we are not trusting God.
Sin separates us from some of the benefits of God’s love. Remember the Prodigal Son was still loved by the father, but didn’t enjoy the benefits of his love when he was in sin.
How easy it is for us to blame our problems on everything except our sin. We will blame God before realising the problem is with us.
But our salvation lies in v20. This could be reworded “I will send My Messiah (The Redeemer) for all humanity, Jesus of Nazareth.”
Then God makes an everlasting covenant with us that the Redeemer will save us from our sins and put His law on our lips and in our hearts, transforming us to be His children forever.
