Backsliding, also known as falling away or described as "committing apostasy", is a term used within Christianity to describe a process by which an individual who has converted to Christianity reverts to pre-conversion habits and/or lapses or falls into sin, when a person turns from God to pursue their own desire. To revert to sin or wrongdoing, especially in religious practice, someone lapses into previous undesirable patterns of behavior. To be faithful, thus to believe backsliding is a reversion, in principle upholds the Apostle Paul’s condition in salvation: "If you declare with your mouth, 'Jesus is Lord,' and believe in your heart that God raised him from the dead, you will be saved."
