Why is the Old Testament relevant for Christians today?

The account of Elisha in 2 Kings serves to reveal God's sovereignty, grace, and the seriousness of sin, which remains relevant for Christians today. It reminds believers of God's power to heal and restore, as seen in the miracle concerning the poisoned waters, a symbol of Christ's redemptive work. Furthermore, the narrative underscores key themes such as judgment, mercy, and the need for faith, all of which are vital parts of the Christian faith. The Old Testament complements the New, enriching our understanding of God's ongoing plan for redemption.
