"To be a Christian means to forgive the inexcusable because God has forgiven the inexcusable in you," said CS Lewis.

Forgiveness is at the heart of the Christian faith. God sent his only son to take the weight of our sin and die in our place, that we might be forgiven, be intimately connected with our Father, and have eternal life. But there's also a call on Christians to forgive others, too – which isn't always easy to obey.

Here are 10 Bible verses to remind you of God's mercy, as well as the importance of learning to exhibit grace ourselves.

Ephesians 1:7-10

"In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God's grace that he lavished on us. With all wisdom and understanding, he made known to us the mystery of his will according to his good pleasure, which he purposed in Christ, to be put into effect when the times reach their fulfilment — to bring unity to all things in heaven and on earth under Christ."

Matthew 6:14

"For if you forgive other people when they sin against you, your heavenly Father will also forgive you."

"The Lord is compassionate and gracious, slow to anger, abounding in love. He will not always accuse, nor will he harbour his anger forever; he does not treat us as our sins deserve or repay us according to our iniquities.
