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

Ephesians 1:4 states that we are 'holy and without blame before Him in love.' This truth is further confirmed by the atoning work of Christ, who bore our sins at Calvary. God views believers through the lens of Christ's righteousness; He sees us as His children rather than as sinners. This perspective, upheld by Scripture, ensures that believers possess a firm hope of salvation and a relationship with God free from condemnation. It's vital for us to grasp that this mercy is not based on our actions, but solely on God's grace manifested in Christ.
