When we meet suffers of depression, we must be extremely careful not to blame them for not having confessed their sins! Nor should we just conclude that they are wicked people, and that is why they are in distress. It is unfortunate that many people seem to be able to offer concern and understanding to those suffering from an organic malady, true clinical depression, but tend to be quite judgmental in dealing with mental or emotional turmoil brought about by their own wrong actions.
There are people who having confessed their sins, still suffer greatly from a sense of guilt. They often feel unworthy of forgiveness and lament the horrible suffering that they have brought through their sins, even though they have confessed and are, by faith, forgiven by God. This too can be a great source of emotional distress. In such cases, it is important to focus on Godís promises of healing and of acceptance, even for the worst of sins.
We canít undo the past; what we can do by Godís grace, is to learn from our past mistakes and make restitution for whatever wrong we have done. We need to surrender ourselves to God and seek His mercy, grace, and healing.
