The thing about the Bible is forgiveness. We must learn how to forgive one another. Forgiveness frees the heart from all kinds of grudges. We need to genuinely forgive others for the work that they have done to us as children of God.
Forgiveness does not come that easily, if you might know, particularly when injury is very severe. But God desires people to keep forgiving. We understand we should not only be ready to forgive people who have wronged us, but also those who have made peace with us. Jesus made it clear that people should forgive one another.
Matthew 6:14-15, which is that, Forgive ye their trespasses. I see every father has also forgiven. But this shows that forgiveness is not an aspect that God requires us to do. Within this test, it reminds us that forgiveness is not a choice of Christians.
It is a command that indicates the mercy that God has toward us. When we forgive and forget, it does not mean that we are letting go of all bad things or do not know the bad things that have been done to us. We are just ignoring the painful experience as human beings.
In this situation, the Bible just advises us to forgive and forget about bitterness. It tells us to love one another. We must remember the things that have been done to us. Authentic forgiveness also makes the heart calm and makes us lead.
