In his talk "Receiving a Testimony of Light and Truth," President Uchtdorf gives us a formula, a spiritual "experiment" to try out, that will help us to receive a testimony of our own.
I really want my children to understand and get experience with this "4-Step Experiment":
1. Search the word of God with sincere desire.
2. Ponder, fearlessly strive to believe.
3. Ask Heavenly Father in the name of Jesus Christ to manifest the truth to you.
4. Do God's will.
To me, step #4 is imperative. If any man will do His will they will know that the doctrine is true. And many of us stumble because we do not perform step #1 correctly, because instead of searching God's words in scriptures and in the words of living prophets, we search for wisdom of the world on the internet. Let's not mess this up. The steps to follow are very clear.
Search. Ponder & strive to believe. Ask God in Christ's name. Do His will.
The other line I like from this talk is, "You need to learn to listen to His voice..."
President Uchtdorf says, "God cares about you. He will listen, and He will answer your personal questions. The answer to your prayers will come in His own way and in His own time, and therefore, you need to learn to listen to His voice. God wants you to find your way back to Him, and the Savior is the way."
To play off of this idea that we need to work to learn to listen to His voice, we curled up our notes into megaphones. We used duct tape to make them pretty and the kids practiced listening to my voice through their amplifiers. If my voice was too soft for them to hear, they could move to be closer to me or turn off external noises that were making it hard for them to hear me. This is a lesson for us all in learning to hear the voice of the Lord in our lives.
