What assurance do we have of eternal life as believers?

The assurance of eternal life for believers is firmly rooted in the promises found in scripture, specifically Revelation 21:7, which states, 'He that overcometh shall inherit all things.' This assurance is not based on our merit but entirely upon the grace of God given through Christ. As we put our faith in the finished work of Jesus, we are granted the status of overcomers, inheriting eternal life as sons and daughters of God. Thus, our confidence comes from believing in God's promises and relying on His grace.
