For [the Mirror] show things that were, and things that are, and things that yet may be… Some never come to be, unless those that behold the visions turn aside from their path to prevent them. The Mirror is dangerous as a guide of deeds – J. R. R. Tolkien
Imagination and memory are a powerful combination. One allows us to plan, the other, to reflect. Together, they can allow an individual to access information God sought to protect them from: the horrors of a life without Him, or their destiny if they had misused His gifts. While this combination can be used to imagine a terror that drives someone closer to God, it is best to avoid this lest it become a stumbling block of guilt and shame. Instead, allow God to present you with the terror of lacking Him should He choose. Only use it as a part of your testimony if it is clear to all who meet you the direction you were headed, such as a drug addict testifying God saved him from homelessness. Otherwise, these extrapolations can easily begin to glorify satan, rather than God – extoling the power of sin, rather than the Cross. Christ is the author and perfector of our faith. Why create a different story than the one He writes with our surrender?
“I know that you can do all things; no purpose of yours can be thwarted; you asked, ‘Who is this who darkens counsel without knowledge?’ But I have declared without understanding things too wonderful for me to know. You said, ‘Pay attention, and I will speak; I will question you, and you will answer me.’ I had heard of you by the hearing of the ear, but now my eye has seen you. Therefore I despise myself, and I repent in dust and ashes!—Job 42:2-6
