Sandy stresses the urgency of forgiveness because time is short and Christ’s return is imminent. Unforgiveness is described as a lifestyle sin that can block spiritual growth, rob believers of God’s blessings, and even leave sin unresolved before death or Christ’s return. The speaker challenges the common excuse of “working on forgiveness,” arguing that forgiveness is a decisive act of obedience empowered by God, not something to be indefinitely postponed.
