What does the Bible say about the hope of Christians?

In Colossians 1:5, Paul refers to 'the hope which is laid up for you in heaven,' indicating that Christian hope is not merely wishful thinking but a firm expectation based on the gospel. This hope is inseparably connected to the truth of the gospel, which reveals salvation through God's sovereign grace on account of the work of Christ. This hope gives believers assurance that they will inherit eternal life, as it is grounded in the righteousness and finished work of Christ, the surety of their salvation.
