Have you experienced Gods forgiveness?
Matthew 6:9 In this manner, therefore, pray: 12 And forgive us our debts,
As we forgive our debtors.
Pray with the attitude of gratitude. We have been forgiven much by God. We in turn, offer that same forgiveness to others, who by the way, owe us far less. We cannot harbor unforgiveness to our brothers or sisters when the LORD released us of our great debt. May dont forgive others because they are yet to recieve forgiveness from the LORD. Mostly, due to pride and ignorance. When I knew I was forgiven much, it was much easier to impart forgiveness.
