We are all imperfect people living in an imperfect world. A world that is sin-saturated and full of brokenness, so despite our Christian Checklists and best efforts to avoid the gaps, each and every person will spend some amount of time treading through gaps of some type during their life.
Gaps do not discriminate:
Christian and unbeliever,
Young and old,
Rich and poor,
Healthy and sick.
At one time or another, we will all experience a gap.
