In this article from the October 1989 Ensign, President Ezra Taft Benson discusses the principles that can help church members repent and come unto Christ.
He said this about trusting the Savior: "Faith in the Lord Jesus Christ is the foundation upon which sincere and meaningful repentance must be built. If we truly seek to put away sin, we must first look to Him who is the Author of our salvation."
