How do we know that the promise of inheriting the earth is true?

The assurance of inheriting the earth lies in the broader biblical narrative regarding God's ultimate plan for creation. While today the earth is marred by sin, the promise pertains to the new heaven and new earth that God will establish. This promise is echoed in Scripture, particularly in Psalm 37:11, which states that 'the meek shall inherit the earth.' Therefore, as believers submit to God and exhibit meekness, they can confidently anticipate this future inheritance where they will experience the fullness of peace and righteousness.
