How many times do we need to forgive?

 Matthew 18:21-22

 ²¹ Then Peter came to Jesus and asked, “Lord, how many times shall I forgive my brother or sister who sins against me? Up to seven times?”  ²² Jesus answered, “I tell you, not seven times, but seventy-seven times.^[a]

Footnotes: 
Matthew 18:22 Or seventy times seven means 70 x 7= 490 times

 The Bible says that Jesus taught us to pray like this: 
"Forgive us for the wrong things that we do. Other people do wrong things to us. But we know that we also must forgive those wrong things.
Forgive people when they do wrong thins to us. If we forgive them. Our father in heaven will also forgive us. But if we do not forgive them. Our father will not forgive us."
