Here is an excellent essay on the issue of "unconditional forgiveness" and the horrible effects it regularly has upon those who preach it and practice it.
Automatic forgiveness packs unforgiveness. It redefines forgiveness as far less than what it means biblically. It hardens hearts with bitterness, isolation, and pessimism. In contrast, conditional forgiveness centers on the Cross. It offers the Gospel to all, recognizes that because of Christ any offender can be forgiven, believes that all relationships can be redeemed, and rests knowing that justice will be served.
