Strange as it may seem, Christians need the gospel as much as unbelievers do. We do not need the gospel to “be saved”. We need the gospel to keep us from lapsing into a performance mind-set in our day to day relationship with God. We need the gospel to remind us that we are still practicing sinners whose only hope for both eternal life and today’s blessings from God are “Jesus’ blood and righteousness.”
