How do we know that the righteous will experience eternal joy?

The confidence in the eternal joy awaiting the righteous comes from the promises articulated in Scripture, particularly in passages such as Matthew 25:46. The righteous man, upon death, is depicted as being greeted by angels and bearing witness to the well-done commendation from God. This assurance of eternal life and joy stems from the character of God Himself, who promises that those who are faithful and live righteously will reap eternal rewards.

Furthermore, the righteousness attributed to believers hinges on their faith in Christ, and it is through this faith that they are counted amongst the righteous. Their struggle against sin on earth and their desire to seek holiness indicate their true relationship with God and solidify the hope they possess for an everlasting communion with Him. The Scriptures depict a future where they will fully attain the holiness they long for, living in direct presence of God, filled with joy and glory for all eternity.
