Why is fully preaching the gospel important for Christians?

Fully preaching the gospel is essential as it encompasses the entirety of God's revelation and the work of Christ. It involves declaring God's sovereignty, our depravity, Christ's redemptive work, and the role of the Holy Spirit. When Paul stated he had 'fully preached the gospel of Christ' (Romans 15:19), he indicated that he held nothing back and ensured that all aspects of God's truth were conveyed. This full presentation is crucial for believers to understand the depths of God's grace and justice and why we cannot add to or subtract from the gospel message. In doing so, we prepare ourselves and others to recognize the fullness of their need for Christ and the assurance of salvation that comes through Him alone.
