First of all, financial wealth is not success, right? ...'easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of heaven'. Secondly, confessing sins can be construed as an act of works and thus, is antagonistic to faith. And, one cannot even recall, recognize or identify all his sins, anyhow. So, i can't imagine that confession is requisite to salvation. In that one's repentance is quite evident by accepting Christ as Lord & Saviour, this is the implication of the abrogation of the law and faith in Christ. By confessing Christ as Lord, you have tacitly confessed your past, present & future sins, have you not?
