Many believers feel they have damaged their memories through past experiences with drugs, alcohol, prescribed medication, immoral living, or wrong decisions. This is not true. These things may suppress the memory, but they cannot permanently harm it. Just as years of wrong decisions may have suppressed the memory, so can God's righteousness heal it.
Often people will condemn a person for what happened in the past. In John 8, the Pharisees and scribes were the accusers of a woman who had committed adultery. Jesus said, "He that is without sin among you, let him first cast a stone to her" (John 8:7). After this statement, the accusers left one by one. The woman did not make an excuse for what she had done. She realized the first of eternal life through Jesus Christ. The woman called Jesus Lord. Not teacher, but Lord. She caught a glimpse of His righteousness and the cleansing power behind it. People often make excuses of their sin. This woman did not; she recognized her sin as evil. Jesus had worked in this woman's heart. She said, "No one condemns me." And Jesus answered; Neither do I condemn you." The Lord did not condone her sin, but He gave her the free gift of righteousness.
When God's righteousness is in our midst, our accusers will leave. We do not need to live in the effects of the past, for this righteousness has been imputed to us, not based on our performance, but upon God's grace.
