Both the Pharisees and Jesus wanted people to live rightly before God in a sin-ruined world. However, their approach was different from each other. Basically, the Pharisees saw sin as a crime to be punished and Jesus saw sin as a sickness that needed healing. You can see this contrasted by how they both saw and treated people.
The Pharisees were always eager to point out other people's sin and make them pay for it. They did it because they felt they had the "God-given" right to carry out judgement and punishment on His behalf. Being God in human flesh (1 John 1:1, 14; 8:58; Colossians 2:9), Jesus knew how sinful and guilty humanity is, however, He did not come to accuse or condemn anyone for their sin. Rather, He came to forgive people and take away their sin.
7 In Christ we are set free by the blood of His death, and so we have forgiveness of sins. How rich is God’s grace. Ephesians 1:7, New Century Version
Forgiveness of sins brings healing and wholeness.
When we appreciate how we are truly forgiven of all our sins, we are set free to enjoy a healthy relationship with God. The Pharisees were right about the problem of sin, but their approach was unhealthy and wrong. They demanded people to earn God's favour, hoping the good they did would outweigh the bad they had done. Jesus, on the other hand, offered rest to those who were laden down with sin. This demonstrated the richness of God's grace.
God's grace is something we can never earn, but something we will always need. Grace changes the way we view God. Instead of seeing Him as an angry Divine Being, we have come to know Him as our Loving Father. This provides the basis for us to build strong and enduring relationships with those who matter most to us. In other words, Christ's forgiveness gives us grace and freedom to love others, in the same manner to how we have first received love from God.
What are the spiritual benefits of knowing that I have been forgiven of my sin?
