Backsliding, also known as falling away or described as "committing apostasy", is a term used within evangelical 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.
An old preacher used to say that if you are not moving toward Jesus, you are moving away from Him—there is no middle ground, no drifting. "Backsliding," in Christianity, is moving away from Jesus after being near Him.
My best description of backsliding is Backsliding simply means to lose God and not to miss Him.
Know this: backsliding doesn't mean a person loses their salvation. The Bible makes it clear that once we are saved, that is, we've put our faith in Jesus as the Son of God who came to die on the cross in our place and rise from the dead, we are saved for good
