“My conscience is clear because I follow some practices of Buddhism.”
A rapist can tell the judge that his conscience is clear because, in his mind, the woman he raped asked for it by her provocative dress. A clear conscience isn't the issue. On Judgment Day forgiveness of sins is the only thing that will matter. It will be the difference between innocent or guilty, life or death, Heaven or Hell. Forgiveness of sins can only come through the cross.
