Sin is the brokenness of us and our world. Sin is both actions/thoughts/desires that we do that hurt our relationship with God, others, and ourselves and Sin is those things we know we should do and fail to do. We believe and confess that all human beings are sinners in need of God's forgiveness, healing, mercy, and love. Thankfully God made forgiveness available to everyone through Jesus Christ who lived a sinless life for the sake of the world.
"But now, apart from law, the righteousness of God has been disclosed, and is attested by the law and the prophets, the righteousness of God through faith in Jesus Christ for all who believe. For there is no distinction, since all have sinned and fall short of the glory of God; they are now justified by his grace as a gift, through the redemption that is in Christ Jesus." - Romans 3:21-24
