Albert Martin:
“The one who forgives makes a solemn four-pronged promise. When you say to someone who has asked your forgiveness for a specific sin, ‘I forgive you,’ you are making this promise:
1. I will not knowingly remember this thing against you.
2. I will not speak of this thing to any others.
3. I will not raise it with you again.
4. I will not allow it to be a barrier in the restoration of our relationship.”
Mike Riccardi:
“Otherwise sound Bible teachers disagree on this point, namely, whether mutual forgiveness (sinner to sinner) is to be conditional (as is God’s forgiveness of us, conditioned upon genuine repentance) or unconditional (unlike God’s forgiveness of us).
I am one who takes the former position: that the Bible makes a distinction between the disposition or readiness to forgive (e.g., Ps 86:5) and forgiveness itself, and instructs us to always cultivate that disposition or readiness to forgive, such that there is never any bitterness or vengeance in the heart, and such that the moment that forgiveness is genuinely sought from us we grant it eagerly from the heart.
But at the same time, I believe the Bible teaches that the actual conferral of forgiveness, by definition, only happens when an offending party confesses and seeks forgiveness from an offended party. I base that on a couple of strands of biblical teaching.
1. The distinction between the readiness to forgive and forgiveness, as above.
2. The consistent teaching that God’s forgiveness of sinners (which is conditioned upon the sinner’s confession and repentance) is to be the pattern of our forgiveness of one another—not only explicitly in passages like Eph 4:32 and Col 3:13, but also indicated by the fact that the very same terms are used for God’s forgiveness of us and our forgiveness of one another. If God does not confer forgiveness upon any except those “who call upon” Him, but rather stands “ready to forgive” them (Ps 86:5), then this ought to be our practice as well.
3. Luke 17:3-4 seems to me to be the clearest passage in which this topic is dealt with, and Jesus’ instruction is explicitly conditional: Be on your guard! “If your brother sins, rebuke him; and *if he repents*, forgive him. And if he sins against you seven times a day, *and returns to you seven times, saying, ‘I repent*,’ forgive him.” Here, forgiveness is explicitly conditioned upon repentance. I simply cannot square the teaching of unconditional forgiveness with the “if-then” conditional statements in this passage.
But again, let me repeat: this does not mean I think we should cherish an unforgiving spirit or nurse resentment against someone who has sinned against us but who hasn’t come to seek our forgiveness. Both I (who think forgiveness is conditional) and the one who thinks forgiveness is unconditional believe that the Christian’s behavior should look exactly the same in this scenario—cultivating a cheerful disposition and readiness to forgive, eliminating any vengefulness or bitterness in their spirit against the other person, behaving happily and without rancor toward him even before he asks forgiveness. The only difference is in what we call that behavior (readiness to forgive vs. forgiveness itself); there’s no distinction in any behavior itself.”
