We need to turn to God and ask for strength to tread this path, so that we may offer forgiveness, acceptance and love to others. Only God knows and understands others, so rather than trying to analyze their motives, we need only to be accepting and forgiving. God has never refused forgiveness to any person, nor turned away from any. There can be no peace without forgiveness. Forgiveness does not erase the past, nor can forgiveness change it.
Forgiveness empties the bitterness from our lives.
Bitterness left to fester will erode our attitudes, our rationale and motives and our relationship with God. To be able to accept God's forgiveness we must be free in ourselves to offer forgiveness to others. We must be prepared to offer this forgiveness not only once, but should a memory of the offence be renewed we must offer forgiveness once again - continually. To offer forgiveness continually is to live forgiveness by accepting the rough and tumble of life, by turning disappointments into opportunities. Next to the Blessed Sacrament itself, your neighbour is the holiest object presented to your senses.
