The Bible say about unforgiveness.

The Bible has quite a bit to say about forgiveness and unforgiveness. Perhaps the most well-known teaching on unforgiveness is Jesus’ parable of the unmerciful servant, recorded in Matthew 18:21-35. In the parable, a king forgives an enormously large debt (basically one that could never be repaid) of one of his servants. Later, however, that same servant refuses to forgive the small debt of another man. The king hears about this and rescinds his prior forgiveness. Jesus concludes by saying, “This is how my heavenly Father will treat each of you unless you forgive your brother or sister from your heart” (Matthew 18:35). Other passages tell us that we will be forgiven as we forgive (see Matthew 6:14; 7:2; and Luke 6:37, for example).

Do not be confused here; God’s forgiveness is not based on our works. Forgiveness and salvation are founded completely in the person of God and by Jesus’ redeeming work on the cross. However, our actions demonstrate our faith and the extent to which we understand God’s grace (see James 2:14-26 and Luke 7:47). We are completely unworthy, yet Jesus chose to pay the price for our sins and to give us forgiveness (Romans 5:8). When we truly grasp the greatness of God’s gift to us, we will pass the gift along. We have been given grace and should give grace to others in return. In the parable, we are appalled at the servant who would not forgive a minor debt after having been forgiven his unpayable debt. Yet, when we are unforgiving, we act just as the servant in the parable.

Will we remember our earthly lives when we are in Heaven?

Isaiah 65:17 says, “For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.” Some interpret Isaiah 65:17 as saying that we will have no memory of our earthly lives in heaven. However, one verse earlier in Isaiah 65:16, the Bible says, “For the past troubles will be forgotten and hidden from my eyes.” It is likely only our “past troubles” will be forgotten, not all of our memories. Our memories will eventually be cleansed, redeemed, healed, and restored, not erased. There is no reason why we could not possess many memories from our earthly lives. The memories that will be cleansed are the ones that involve sin, pain, and sadness. Revelation 21:4 declares, “He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away.”

The fact that the former things will not come to mind does not mean that our memories will be wiped clean. The prophecy could be suggesting the wondrous quality of our new environment. The new earth will be so spectacular, so mind-blowing, that everyone will quite forget the drudgery and sin of the current earth. A child who is scared of the shadows in his room at night completely forgets his nocturnal fear the next day on the playground. It’s not that the memories have been wiped out, only that, in the sunshine, they don’t come to mind.
