How Can the Holy God Accept as Righteous Guilty Sinful People?

Sin creates a problem for people because by it we are condemned before God and damned. The Law reveals this but it can not rescue us. Why? Because we are lawbreakers and continue to transgress. Our sin also creates a problem for God who desires to receive us into his fellowship and has chosen us in Christ. How can he righteously forgive us and then treat us as sinless and righteous before him? He cannot maintain his holiness and righteousness unless the sin and the guilty sinners are punished and pay for their sin. God is able to justify, treat as holy and righteous sinners who believe in Jesus. How does God do this? He accomplishes it through the redemption that is in Christ Jesus. He, the Righteous One, took our sin, our guilt, upon himself and paid the debt, endured the curse, and exhausted God'd wrath against us. 2 Corinthians 5:21 states, "For our sake God made Jesus to be sin, the sinless One who knew no sin to be the sinner so that in him we might become the righteousness of God!" God in Christ's atoning death expiates, that is, removes our sin, and in Christ's resurrection life clothes us with his righteousness. It is external to us, a righteousness that belongs to him and his holy righteous life but credited to us! This is the glorious gospel of our Lord!
