How do we know that God's mercy is vital for believers?

God's mercy is not only a comfort but a fundamental necessity for believers. As highlighted in Ephesians 2:1-5, believers were once 'children of wrath' but have been made alive through the mercy of God. This mercy reveals the nature of God’s grace, which not only rescues but also transforms. By receiving mercy, believers recognize their previous state of condemnation and understand their new status as justified in Christ. Without such mercy, they remain under the law's penalty. Thus, God's mercy is fundamental in elevating believers from spiritual death to a living faith filled with hope and assurance.
