Human memory is an incredibly fickle phenomenon. With matters of the spirit in particular, it is so easy to forget the things that we have experienced and believed. Having now, for instance, been a member of the Church for nearly 8 years, it is difficult at times to remember how I thought felt and acted before. Fortunately, I can still remember the incredible joy I felt when I was converted, because I took to heart advice similar to that given by Elder Rasband at conference to strive to remember our sacred experiences.
When I have counseled individuals such as my friend, I have explored their decisions made over the years which led them to forget sacred experiences, to weaken, and to doubt. I encouraged them, as I encourage you now, to recall, especially in times of crisis, when you felt the Spirit and your testimony was strong; remember the spiritual foundations you have built. I promise that if you will do this, avoiding things that do not build and strengthen your testimony or that mock your beliefs, those precious times when your testimony prospered will return again to your memory through humble prayer and fasting. I assure you that you will once again feel the safety and warmth of the gospel of Jesus Christ.
Sacred memories can powerful tool in the fight against doubt and confusion from the adversary. We need to cast our minds frequently on our sacred moments and treasure them. As we do so, we will have confidence that God is operative in our lives. We will know that we were led by him to have certain experiences. We will have confidence that he will be with us no matter what.
When I remember my sacred conversion experiences, I am filled with incredible joy. Remembering helps me to know that I am still on the right path. It helps me to know that God loves me. It helps to heal wounds and silence doubts.
On the other hand, Satan can use our memory to cast doubt and to push us away from God. He can draw to our recollection moments where we have fallen short or felt distant from God. He can lead us to doubt those sacred moments. We can and must prevent him from leading us to question or forget what we have felt.
