From General Conference Message

The Lord does not require perfect faith for us to have access to His perfect power. But He does ask us to believe.
My dear brothers and sisters, my call to you this Easter morning is to start today to increase your faith. Through your faith, Jesus Christ will increase your ability to move the mountains in your life, even though your personal challenges may loom as large as Mount Everest.
Your mountains may be loneliness, doubt, illness, or other personal problems. Your mountains will vary, and yet the answer to each of your challenges is to increase your faith. That takes work. Lazy learners and lax disciples will always struggle to muster even a particle of faith.
To do anything well requires effort. Becoming a true disciple of Jesus Christ is no exception. Increasing your faith and trust in Him takes effort.
Christ Is Risen; Faith in Him Will Move Mountains - Russell M. Nelson
