God has the power to establish us by his grace. Paul’s message in his letter to the Romans: the gospel is the power of God for salvation for anyone who has faith in Jesus. As JI Packer said: ‘God saves sinners’. This transforms the way we live through the Holy Spirit. He is able to establish us, to make firm. We cannot save ourselves. Tim Keller: ‘The gospel is not done by us but done for us’ Jesus has lifted us out of the slimy pit: (Psalm 40:2 – ‘He lifted me out of the slimy pit, out of the mud and mire; he set my feet on a rock; and gave me a firm place to stand’) – he has established us, made us firm in the salvation he has given us.
