Our consciences are a gift from God to alert us to the need for forgiveness. Many people struggle for years with guilty consciences. We have a need to confess, to help get some peace of mind. Our ultimate confession should be straight to God, trusting in Jesus, accepting God's forgiveness on the basis that Jesus took our eternal punishment on the cross, so that we can receive the gift of eternal life. If confessed from a humble and repentful heart, with an eye to the cross of Calvary, we can receive complete forgiveness just like the man in the parable that Jesus spoke of, by praying "God, have mercy on me, a sinner" (Luke 18:13).
