1:3 part 2

Paul wishes the Corinthians to have peace through Christ as well as grace. This peace is "well-being, wholeness, welfare" as Fee says. God's desire is to do good to His children. He always does what is good. His normal desire is to bless His children and work for their welfare. It was only when the nation of Israel turned against God and served evil for hundreds of years that God had to turn against them. But even then, God promised to restore His people and do good to them.

Jesus said that his peace was not the peace of this world, but a peace from him (John 14:27). This is the kind of peace Paul wishes for the Corinthian church.
